Possible ideas from meeting on 2024-04-18 with Favonia:

  • Check in with Axel to see if any of the ideas from last year are still being worked on / need help
  • Port POPL paper to Ocaml
  • Component libraries of the proof assistants (will be much harder, need to figure out what is involved)

As discussed in 2024-05-09 meeting with Favonia, will reconsider focus towards just formalizing some math theorems.

Notes from this morning's meeting with Axel

Notes from this morning's meeting with Axel - Cellular homology - Doing homology rather than cohomology - Loïc Pujet collaborator - CW complexes - doing it differently than paper https://arxiv.org/pdf/1802.02191 - prove that their theory is functorial by comparing it to another cohomology theory - current work is proving functoriality directly - map between 2 cw complexes -> cellular approximation - constructed homology functor - Eilenberg-steenrod axioms - characterizing cohomology theory - dualizing homology - Hurewicz theorem - issue is they have everything in the library - Mayor Vietoris sequence (long exact sequence of cohomology groups - Evan cavallo - formlaized cohomology theory, being a functor that satisfies the eilenberg steenrod axioms - proved if u have cohomology, then u can construct mayor vietoris sequence - IDEA corresponding theory for homology rather than cohomology - construct mayer vietoris sequence - https://ecavallo.net/works/thesis15.pdf - uses some outdated ways of writing proofs in hott - look primarily at the statements - homology axioms - https://arxiv.org/pdf/1706.01540 - definition 1 1 is some of the eilenberg steenrod axioms - some times people functorality assumptions as an axiom - https://en.wikipedia.org/wiki/Eilenberg%E2%80%93Steenrod_axioms - https://ncatlab.org/nlab/show/ordinary+homology - IDEA formalize spectral sequences (Floris van Doorn's PHD thesis) - https://florisvandoorn.com/talks/Bonn2018spectralsequences.pdf - formalized previously, but not in cubical - https://florisvandoorn.com/papers/dissertation.pdf - spectral sequences for homology (instead of cohomology) - nice direction is just computing homology groups of specific spaces - compute cohomology groups, running proof by computation, see if you can actually normalize certain proof termss - https://aljungstrom.github.io/publication/CSL22 - https://arxiv.org/abs/1606.05916 - advice - learn by formalizing more homotopy theoretical mathematics - hatcher
