Sheaf theory

Sheaf of logarithmic differential forms

In algebraic geometry, the sheaf of logarithmic differential p-forms on a smooth projective variety X along a smooth divisor is defined and fits into the exact sequence of locally free sheaves: where are the inclusions of irreducible divisors (and the pushforwards along them are extension by zero), and is called the when p is 1. For example, if x is a closed point on and not on , then form a basis of at x, where are local coordinates around x such that are local parameters for . (Wikipedia).

Akhil Mathew - Remarks on p-adic logarithmic cohomology theories

Correction: The affiliation of Lei Fu is Tsinghua University. Many p-adic cohomology theories (e.g., de Rham, crystalline, prismatic) are known to have logarithmic analogs. I will explain how the theory of the “infinite root stack” (introduced by Talpo-Vistoli) gives an alternate approach

J. Demailly - Existence of logarithmic and orbifold jet differentials

Abstract - Given a projective algebraic orbifold, one can define associated logarithmic and orbifold jet bundles. These bundles describe the algebraic differential operators that act on germs of curves satisfying ad hoc ramification conditions. Holomorphic Morse inequalities can be used to
