Just did, and I can relate...

I also think that incompleteness is worth mentioning, in the context of "what is even possible"

Thanks, now I need to find a numerical linear algebra professor in Heidelberg who will have me for a job talk so I can try this place

Solve math as in: "proving all possible true statement in finite time"?
Two necessary conditions for that are 1. The set of true statements is of finite cardinality 2. Math is complete
(Not sure if sufficient).

For 1. I have no idea... 2. Math is incomplete- not all true statement follow others

Quasitubal Tensor Algebra Over Separable Hilbert Spaces The tubal tensor framework provides a clean and effective algebraic setting for tensor computations, supporting matrix-mimetic features like Singular Value Decomposition and Eckart-Young-like optimali...

New preprint!!! we push tubal tensor algebra to infinite-dimensional tubes, build a quasitubal C*-algebra that supports matrix-mimetic (quasitubal tensor) SVD and Eckart–Young-like optimality. Matrix tricks, now for separable Hilbert spaces. arxiv.org/abs/2504.16231

Now for the important part: where can I find a decent coffee in Heidelberg???

#mathsky I you know. And you know that I know you know.

Underappreciated?! Not in the social circles I am in... we are highly inclusive in case you are thinking about hanging out with us:)
You would have to be able to tell Sherman-Morrison apart from Woodbury formula though... (a line must be drawn somewhere)

Hilbert spaces: no inner product space should allow the existence of a bounded sequence that has no partial (strong) limits.

Show that it is directly implied by the Exterior Anglebra structure of R2

Well, my formal knowledge in physics is just around the corner of F=ma. But Ill give it a shot! Thanks

Tubal Quasi Tensor Algebra In Hilbert Spaces

I hope that soon I'll be able to post a preprint on arxiv. For now I can share an abstract of an upcoming talk:
meetings.siam.org/sess/dsp_tal...

QFT related keywords that I frequently encounter while working on this are: quantum group, tempered distributions, observables, states etc..

Unfortunately, my background in physics is limited to Newton's laws of motion.
I am working on an extension of an algebraic framework (tubal tensor algebra) to infinite dimensions. This extension is mainly motivated by applications in signal processing, control, dynamics, functional data analysis.

#physics feed to the rescue?

Hey #mathsky - can anyone recommend a good intro for quantum field theory? I stumbled on it (at least by title) too frequently while working on seemingly unrelated project so now I'm worried that the two subjects have a trivial connection between them, that you all knew but no one ever told me about

Never imagined something like this could happen: I defined an object I'm interested in as the dual module to something, and it felt surprisingly... right.

Hey!
My name is Uria, and I'm a PhD candidate in applied mathematics.
My main interest is in tensor methods, randomized linear algebra, FDA and their applications.
I promise to share any exiting new results I have, looking forward to learn about yours :)

You know emacs has a package for that... (not really, but I had to say it anyway...)
