Explicit coverings of families of elliptic surfaces by squares of curves

Colin Ingalls, Adam Logan, Owen Patashnick

We show that, for each $n > 0$ , there is a family of elliptic surfaces which are covered by the square of a curve of genus $2 n + 1$ , and whose Hodge structures have an action by ${\mat…

McKay quivers and Lusztig algebras of some finite groups

Ragnar-Olaf Buchweitz, Eleonore Faber, Colin Ingalls +1

We are interested in the McKay quiver $Γ (G)$ and skew group rings $A * G$ , where $G$ is a finite subgroup of $GL (V)$ , where $V$ is a finite dimensional vector space over a f…

Crepant resolutions of double covers: On the Cynk-Hulek criterion for crepant resolutions of double cover

Colin Ingalls, Adam Logan

A collection $S = {D_{1}, \dots, D_{n}}$ of divisors in a smooth variety $X$ is an {\em arrangement} if intersections of all subsets of $S$ are smooth. We show that a double cover of…

$A V$ modules of finite type on affine space

Yuly Billig, Colin Ingalls, Amir Nasr

We study the category of modules admitting compatible actions of the Lie algebra $V$ of vector fields on an affine space and the algebra $A$ of polynomial funct…

Quotient graphs and amalgam presentations for unitary groups over cyclotomic rings

Colin Ingalls, Bruce W. Jordan, Allan Keeton +2

Suppose $4∣ n$ , $n \geq 8$ , $F = F_{n} = Q (ζ_{n} + ζ ˉ_{n})$ , and there is one prime $p = p_{n}$ above $2$ in $F_{n}$ . We study amalgam presentations for $\operatornam…
