comment Duality between Tor and Ext?
After reading some more about this subject and trying to simplify the question as much as possible, I'm starting to think that one could use Universal Coefficient Theorem for cohomology. How exactly, I'm still wondering...

comment On a coalgebra structure of simplicial homology
I was suggested that it has something to do with the Alexander-Whitney diagonal map. Can anyone please expand this notion in this case?

comment Koszul algebras basics
Thank you. I remember having had a look at it, but I'll give it another try, it definitely looks friendly. I'll come back and ask for more help or (hopefully) I'll answer my own question. Thanks again.

Beilinson, Ginzburg and Soergel's article Koszul Duality Patterns in Representation Theory. I used this shorthand notation given the article's popularity in the domain.

Thank you very much for your detailed answer! Indeed, some of these references are familiar to me, especially Loday's book, which I already "went through", especially the first 2 chapters. Also, Ginzburg's lectures is familiar to me. Regarding the others, I will definitely read them, at least to get the "main idea", they seem like excellent references. Again, thank you very much for your time and valuable answer!

I don't make this distinction. What I meant by "the algebraic part" was something different from the C*-theory that Connes and others present. I'll post an answer to clarify it a bit, since in the meantime I got to discuss the problem with a researcher in the field.
