Sheaves for spacetimes: a survey
Pierre Schapira
On a spacetime endowed with a time function (such as a globally hyperbolic manifold) we solve the global Cauchy problem for hyperbolic D-modules in the framework of Sato's hyperfun…
Topologies and sheaves on causal manifolds
Pierre Schapira
A causal manifold is a manifold endowed with a closed proper cone in the tangent bundle such that the projection is surjective when restricted to the…
Mikio Sato, a visionary of mathematics
Pierre Schapira
This paper, to appear in the ``Notices of the AMS'' 2024, is a modified version of a text already appeared in this journal, Feb. 2007 after a first publication in French, in ``La G…
Unusual functorialities for weakly constructible sheaves
Andreas Hohl, Pierre Schapira
We prove that various morphisms related to the six Grothendieck operations on sheaves become isomorphisms when restricted to (weakly) constructible sheaves. To this end, we first s…
A truncated manuscript
Pierre Schapira
A critical essay of the book ``Récoltes et Semailles'' by Alexander Grothendieck, recently published by Gallimard editions.
A property of the interleaving distance for sheaves
Francois Petit, Pierre Schapira, Lukas Waas
Let be a real analytic manifold endowed with a distance satisfying suitable properties and let be a field. In [PS20], the authors construct a pseudo-distance on th…
