Congruence modules and Wiles defects of determinantal rings of maximal minors

Kashif Khan, Aryaman Maithani

Let $O$ be a discrete valuation ring and $A := O [X_{m \times n}] / I_{m} (X)$ the determinantal ring of maximal minors. We consider algebra maps $λ : A \to O$ , which is tantamount…

Constructing Hard Examples for Graph Isomorphism

Anuj Dawar, Kashif Khan

We describe a method for generating graphs that provide difficult examples for practical Graph Isomorphism testers. We first give the theoretical construction, showing that we can…
