Myopic Tutte polynomials and Khovanov homology in
Keegan Boyle, Dean Spyropoulos
We present a "myopic" Tutte polynomial for graphs on which takes only nullhomologous spanning subgraphs as input. It recovers the generalized Krushkal polynomial an…

Plane Floer homology and the odd Khovanov homology of 2-knots

We prove a conjecture of Migdail and Wehrli regarding the odd Khovanov cobordism maps associated to knotted spheres. Our key tool is Daemi's plane Floer homology, which we use in p…
