On a twisted de Rham complex
Claude Sabbah
We show that, given a projective regular function f on a smooth quasi-projective variety over C, the corresponding cohomology groups of the algebraic de Rham complex with twisted d…

Semicontinuity of the spectrum at infinity
Andras Nemethi, Claude Sabbah
We prove that, for an analytic family of ``weakly tame'' regular functions on an affine manifold, the spectrum at infinity of each function of the family is semicontinuous in the s…

Hypergeometric periods for a tame polynomial
Claude Sabbah
We analyse the Gauss-Manin system of differential equations---and its Fourier transform---attached to regular functions satisfying a tameness assupmption on a smooth affine variety…
