Khovanov homology can distinguish exotic Mazur manifolds
A Mazur manifold is a compact, contractible 4-manifold that has a handle decomposition with a single 1-handle and a single 2-handle. We show that Khovanov homology can distinguish certain exotic Mazur manifolds.

Card Dealing Math
Various card tricks involve under-down dealing, where alternatively one card is placed under the deck and the next card is dealt. We study how the cards need to be prepared in the deck to be dealt in order. The order in which the $N$ cards are prepared defines a permutation. In this work, we analyze general dealing patterns, considering properties of the resulting permutations. We give recursive formulas for these permutations, their inverses, the final dealt card, and the dealing order of th…

SET! From Groups to Games
The game of SET is one of the best mathematical games ever. It is no wonder that people have tried to generalize it. We discuss existing generalizations of the game of SET to different groups. We concentrate on two types of generalization: a) where a set consists of cards that multiply to the identity; b) where a set consists of three cards that form an arithmetic progression. We finish with a discussion of some properties of the games that influence how enjoyable they are.

Cobordism maps in Khovanov homology and singular instanton homology II
This paper is a continuation of our previous work, where we defined an embedded cobordism map on the instanton cube complex that recovers the cobordism maps both in Khovanov homology and singular instanton theory. In this paper, we extend this construction to immersed cobordisms. As an application, we show that, for any smooth, oriented (not necessarily ribbon) concordance $C$ from a two-bridge torus knot, the induced map $\widetilde{Kh}(C)$ on reduced Khovanov homology is injective, with the l…
