An Explicit Derived Equivalence of Azumaya Algebras on K3 Surfaces via Koszul Duality
Colin Ingalls, Madeeha Khalid
We consider moduli spaces of Azumaya algebras on K3 surfaces and construct an example. In some cases we show a derived equivalence which corresponds to a derived equivalence betwee…
Graph pegging numbers
Geir Helleloid, Madeeha Khalid, David Petrie Moulton +1
In graph pegging, we view each vertex of a graph as a hole into which a peg can be placed, with checker-like ``pegging moves'' allowed. Motivated by well-studied questions in graph…
Rank Two Sheaves on K3 Surfaces: A Special Construction
Colin Ingalls, Madeeha Khalid
Let X be a K3 surface of degree 8 in P^5 with hyperplane section H. We associate to it another K3 surface M which is a double cover of P^2 ramified on a sextic curve C. In the gene…
Lagrangian curves on spectral curves of monopoles
Brendan Guilfoyle, Madeeha Khalid, José J. Ramón-Marí
We study Lagrangian points on smooth holomorphic curves in T equipped with a natural neutral Kähler structure, and prove that they must form real curves. By virtue o…
On K3 Correspondences
Madeeha Khalid
We consider relationships between families of K3 surfaces, in the context of string theory. An important ingredient of string theory also of interest in algebraic geometry is T-dua…
