4. Resolutions

    1. Compare \Delta-resolutions


      Add remark

      Problem 4.1.

      Can we directly compare the Hanlon-Hicks-Lazarev and Brown-Erman construction of resolutions?

      \bullet Potential mechanism: (starting in degree 0)

      {vertices/points in stratification of T^n arising in HHL} is in one to one correspondence with {additional generators for normalization of the semi-group ring, i.e. elements coming from saturation of semigroup}

        • Topology/Morse theory of cellular resolutions


          Add remark

          Problem 4.2.

          Can we interpret resolutions via Fukaya categories? (e.g. minimizing resolutions through "cellular" operations)

            • Topology/Morse theory of cellular resolutions


              Add remark

              Problem 4.3.

              The Morse-theoretic description of H_*(M) can be refined (at e.g. level of "framed flow categories"). can this refined decomposition tell us something on the algebraic side?

                •     T^n=K(\pi,1)

                  Add remark

                  Problem 4.4.

                  Given a cellular resolution, is there a meaningful way to algebraically interpret topology of the cell complex beyond homology e.g. \pi_1?

                    • Topology/Morse theory of resolutions


                      Add remark

                      Problem 4.5.

                      Is there an analogue of "Morse theory for cellular resolutions" for virtual resolutions?

                        •     Observation: The current definition of virtual resolution is so broad and it is not meaningful to parameterize, then.

                          Add remark

                          Problem 4.6.

                          Is there a well-behaved moduli theory of virtual resolutions equipped with extra structure? e.g. condition under which there exists a finite set? or space/ stacks/...? (c.f. [Boij-Sölderberg] theory constructs a meaningful cone of Betti tables of all free complexes. Look at subcone of virtual resolutions of a given M)
