 arsaw/2/">Floer homology via semi-infinite dimensional cycles</a>\nby Piot
 r Suwara (MIT) as part of Knot theory seminar in Warsaw\n\n\nAbstract\nFlo
 er's idea of constructing a Morse-Smale-Witten chain complex to compute th
 e "middle-dimensional homology" of infinite-dimensional spaces led to the 
 emergence of groundbreaking invariants of knots\, low-dimensional manifold
 s and symplectic manifolds\, collectively known under the name of Floer ho
 mology. I will describe a construction of a homological invariant of infin
 ite-dimensional spaces with a functional facilitating what Atiyah called "
 semi-infinite dimensional cycles"\, following the work of Lipyanskiy and b
 ased on earlier work of Mrowka and Ozsváth. The construction reduces the 
 analytical difficulties needed to define Floer homology and hopefully will
  provide a convenient framework for constructing equivariant Floer homolog
 ies.\n

 nby Józef Przytycki (The George Washington University) as part of Knot th

 r operators yielding the Jones and\nHomflypt polynomials.\nWe adjust these
  Yang-Baxter operators constructed by Jones so the\nhomology theory given 
 by Victoria Lebed and the speaker could be used.\nThen we compute the seco
 nd homology for this family of Yang-Baxter\noperators. It has the potentia
 l to yield a 2-cocycle invariant for links.\nSee arXiv:2004.07413 <https:/

 ranched covers)\ncan be conveniently used in studying concordance question
 s of knots and\nthe standard three-sphere. Motivated by involutive Floer h
 omology (and\nmore generally\, by connected Floer homology) we introduce a
 n invariant\nof knots using the double branched cover (and its involution)
  in an\nessential way\, and show some new independence results in the\ncon
 cordance group.\n

 bstract\nDoes every Jordan curve in the Euclidian plane contain 4 points t
 hat form\nthe corners of a square? What about the corners of a rectangle w
 ith a\nprescribed aspect ration?\nStarting from this old metric problem po
 sed by Toeplitz over a hundred\nyears ago\, we discuss problems in knot co
 ncordance theory.\n\nFollowing a strategy of Hugelmeyer\, we relate Toepli
 tz's question to the\nfollowing variant of a classical knot concordance qu
 estion:\nFor a given knot \\(K\\) in the 3-sphere \\(S^3\\) (or \\(S^2 \\t
 imes S^1\\))\, what is the smallest\ninteger among the first Betti numbers
  of non-orientable surface in the\n4-ball \\(B^4\\) (or \\(B^3 \\times S^1
 \\)) with boundary \\(K\\)?\nWe discuss this in both the smooth and topolo
 gical category. Along the way\,\nwe note that a celebrated result by Batso
 n on the smooth non-orientable\n4-genus of torus knots does not hold in th
 e topological category.\n\nBased on joint work with Marco Golla\; see\nhtt

 y Boyu Zhang as part of Knot theory seminar in Warsaw\n\n\nAbstract\nKhova
 nov homology is a combinatorially defined invariant for knots and links. I
 n this talk\, I will present several new detection results for Khovanov ho
 mology on links. In particular\, I will present a classification result fo
 r all n-component links whose Khovanov homology has the minimum rank 2^n. 
 The classification gives a positive answer to a conjecture of Batson and S
 eed\, and generalizes the unlink detection theorem of Hedden-Ni and Batson
 -Seed. The proof is based on a new excision formula for singular instanton
  Floer homology. This is joint work with Yi Xie.\n
