On the $b$ -functions of hypergeometric systems

Thomas Reichelt, Christian Sevenheck, Uli Walther

For any integer $d \times (n + 1)$ matrix $A$ and parameter $β\in\CC^d$ let $M_{A} (β)$ be the associated $A$ -hypergeometric (or GKZ) system in the variables $x_{0}, \dots, x_{n}$ . We describ…

Survey on the $D$ -module $f^{s}$

Anton Leykin, Uli Walther

In this survey we discuss various aspects of the singularity invariants with differential origin derived from the $D$ -module generated by $f^{s}$ .

The Jacobian module, the Milnor fiber, and the $D$ -module generated by $f^{s}$

Uli Walther

For a germ $f$ on a complex manifold $X$ , we introduce a complex derived from the Liouville form acting on logarithmic differential forms, and give an exactness criterion. We use t…
