On non-isotopic spanning surfaces for a class of arborescent knots
Lawrence Roberts
We use the methods of Hedden, Juhasz, and Sarkar to exhibit a set of arborescent knots that bound large numbers of non-isotopic minimal genus spanning surfaces. In particular, we d…

A type A structure in Khovanov Homology
Lawrence P. Roberts
Inspired by bordered Floer homology, we describe a type A structure on a Khovanov homology for a tangle, which complements the type D structure in a previous paper. The type A stru…

A type D structure in Khovanov homology
Lawrence P. Roberts
We describe the first part of a gluing theory for the bigraded Khovanov homology with integer coefficients. This part associates a type D structure to a tangle properly embedded in…
