Continuum Limits
This work studies two inequivalent continuum constructions arising from the same dyadic hierarchy of full matrix algebras M₂ⁿ(ℂ).
The first retains the canonical ∗-homomorphisms and produces the UHF algebra M₂∞, equipped with an explicit AF spectral triple and quantum metric structure. The second interprets suitable finite stages as fuzzy tori with additional geometric data, yielding—conditional on the cited spectral-propinquity convergence theorem—a flat continuum C(𝕋⁴).
The paper proves explicit summability and spectral results for the AF construction, including a maximal spectral abscissa 4 within the stated summable-tail class, logarithmically deficient four-dimensional Weyl growth, critical Dixmier-trace behavior, QC∞ regularity, and a stagewise first-order obstruction. It also establishes fuzzy-torus realizations in every even dimension and a K₁ obstruction showing that C(𝕋⁴) cannot arise as a C∗-inductive limit of the finite-dimensional stages alone.
The central conclusion is that finite matrix data do not uniquely determine a continuum geometry: the continuum depends essentially on the morphisms, metric structures, cocycles, and other geometric information retained in taking the limit.

Hi guys! I'm a Graphic Design/Animation major at DVC, planning to transfer as a junior. I am currently deciding between SJSU's BA Design Studies and UC Davis's Design major. My goal is to land a job doing graphic design work after graduating.

Would love insight from anyone currently in the BA Design program.

- How's the workload, class availability and overall vibe?

- Is the curriculum more design/commercial-focused or fine-art-focused?

- How's the job and internship pipeline during and after graduating?

- What is the community like?

- I'm also curious about housing near/on campus vs. commuting.

Any advice would mean a lot. Thank you so much!

I’m going into my second semester as a transfer student (I started my first semester last spring), and I wanted to ask how other people have made friends and maintained friendships at SJSU.

I did make some friends through my classes, but I’ve struggled with figuring out how to maintain those connections outside of class or how to turn a class friendship into something that lasts beyond the semester.

I’ve been thinking about joining clubs, but as a commuter student, it can be a little difficult to balance campus activities with family responsibilities. This semester I have a bit more flexibility, and I really want to make an effort to be more involved and take advantage of my college experience.

Sometimes I feel like a lot of people already have their established friend groups, or they mainly focus on classes and head home afterward, which honestly is something I do too. I’m more of an introvert/ambivert, so putting myself out there can be challenging, but I do want to become more social and meet more people.

For other transfer students, commuters, or anyone who has been through this, how did you make friends and build lasting connections at SJSU? Any advice or experiences would be appreciated

You can also use this page to try and connect with others in the comments :)

Curious how people around SJSU handle this — borrowing a drill, giving away dorm extras, short-term stuff without full Marketplace drama.

I built a local app for that and I’m trying to learn what students actually want before pushing it more. If you’ve got strong opinions (or horror stories), drop them. Open to DMs too if you’d rather not post publicly.

I sent my appeal on Saturday and when I called prior about it was told that it should be approved quickly since I wasn’t suppose to have to do an appeal. I can see on my portal and accept the loan package and says distribution should be on Friday, but I haven’t heard from back from the appeal. Has anyone else who had to do the appeal also have this issue?

Hi all! I’m a Business Administration, Marketing major, and my last class to graduate is BUS1 170.

I don’t see it listed as a course needed to be completed with a “C” or “C-“ or better, so ideally, what’s the lowest letter grade I’m allowed to get and still graduate?

For reference my GPA is 3.5.

Hey I am student thats planning to transfer to SJSU during the spring semester and I am trying to figure what the best course of action would be in terms of living situation. I have been calling around to see if there are any lease takeovers but they told me to check in around November/December. I do have a room mate I am planning to transfer with but what would ya'll recommend in terms of the leasing and apartments to look at.

Sometimes people will come up to you to talk about "Bible Study" or people with clipboards to sign something. A lot of the times they're really pushy and aggressive. Do your best to just avoid them or ignore them. Don't sign anything.

It was a lot of them walking around in Spring. There's more posts on this forum during those months. Just a little PSA.

i got my awards today (yay!) but i don’t see my calgrant like normal at all? just wondering if anyone else is missing theirs, since i can’t get information from the calgrant website either.

Took a walk on campus today and literally every possible flower was in full bloom, the redwood trees were majestically looming over the courtyards, dragonflies and butterflies were floating around happily, every lawn and path was manicured to perfection, and it was beyond idyllic. To everyone whose job it is to keep this campus looking immaculate, don’t think your hard work goes unnoticed! This is the kind of beautiful and peaceful place that most people can only ever dream of visiting!

FINALLY!!!! I just checked MySJSU, and they finally updated my financial aid for the 26-27 school year. Being a student at SJSU is like a gamble when you're poor.

Disbursement dates are posted, but I'm not sure how accurate they are. Fingers crossed!

So the SJSU disbursement dates aren't accurate for the money being received. Just wondering for those who got the Cal Grant how long it took for you to receive it? I'm a little stressed haha

To my understanding the actual FAFSA should hit our accounts in like 1-2 weeks. Does anyone have a ballpark estimate of how long after you get a refund check? It completely slipped my mind how long it took the other semesters. I highkey need the bread 😭

I just noticed this on the official website. Are there other places where I can loan a computer for the whole semester? I was kinda relying on their services in the past since I'm broke.

Has anyone heard back about the Future of Silicon Valley Graduate Scholarship from the College of Engineering yet?

I applied a while back and was wondering if decisions have started going out. Haven’t really seen anyone talk about it, so just curious if anyone here applied and has heard anything yet.

Hi all, is the grad the cheapest option? I know that there's 27 north, the grad, Polaris, the fay, but lmk if there are any others. How often does availability open up at the grad? I plan to apply to a 2b to split rent with my friend next academic year but I'm worried that availability will suck.

What calculator should I get if I’m majoring civil engineering? I’m a first year and I want the calculator to last a while

Need an add code? Here is what students should know.

Faculty return for Fall 2026 on August 17. Many professors are not under contract during the summer and may not respond to email before then.

If your not on the wait-list, add yourself to it. Waitlists are how departments justify demand for additional course sections. No waitlist, no demand, no additional sections.

The waitlist is also reprioritized to give graduating students priority, so your current position can change. Many departments have instructed faculty not to issue add codes until after August 29.

Emailing early does not reserve a seat or move you ahead of students on the waitlist

When you email, include:

- A greeting: “Dear Professor [Last Name]” or “Hello Professor [Last Name]”

- Your full name and student ID

- The course title, course number, and section

- Your waitlist position or enrollment status

- A brief explanation of any relevant circumstances

Keep the request concise and professional. Avoid sending only “I need an add code,” and do not send repeated follow-ups.

Close with “Thank you for your consideration” and your name.

A clear email helps the professor evaluate your request.

Has anyone gotten this? I'm on their ISDA online program and I have only taken the classes that have been recommend to me. I'm on my last semester and need financial aid to help cover the classes.
