Instantons, special cycles, and knot concordance
Aliakbar Daemi, Hayato Imori, Kouki Sato +2
We introduce a framework for defining concordance invariants of knots using equivariant singular instanton Floer theory with Chern-Simons filtration. It is demonstrated that many o…
Weak extension theorem for measure-preserving homeomorphisms of noncompact manifolds
Tatsuhiko Yagasaki
In this paper we introduce a general notion of weak extension property for embeddings induced by a group actions. As an example, for the group H(M, m) of measure-preserving homeomo…
Groups of volume-preserving diffeomorphisms of noncompact manifolds and mass flow toward ends
Tatsuhiko Yagasaki
Suppose M is a noncompact connected oriented C^infty n-manifold and omega is a positive volume form on M. Let D^+(M) denote the group of orientation preserving diffeomorphisms of M…
Groups of measure-preserving homeomorphisms of noncompact 2-manifolds
Tatsuhiko Yagasaki
Suppose M is a noncompact connected 2-manifold and m is a good Radon measure of M with m(partial M) = 0. Let H(M)_0 denote the identity component of the group of homeomorphisms of…
Homotopy types of the components of spaces of embeddings of compact polyhedra into 2-manifolds
Tatsuhiko Yagasaki
Suppose M is a connected PL 2-manifold and X is a compact connected subpolyhedron of M (X \neq 1pt, a closed 2-manifold). Let E(X, M) denote the space of topological embeddings of…
