Abstract We show the existence of prime divisors computing minimal log discrepancies in positive characteristic except for a special case. Moreover we prove the lower semicontinuity of minimal log discrepancies for smooth varieties in positive characteristic if the exponent of an ideal is less than the log canonical threshold of the ideal.

Inversion of adjunction for quotient singularities
We prove the precise inversion of adjunction formula for quotient singularities and klt Cartier divisors. As an application, we prove the semi-continuity of minimal log discrepancies for klt
Divisors computing minimal log discrepancies on lc surfaces
Let (X ∋ x,B) be an lc surface germ. If X ∋ x is klt, we show that there exists a divisor computing the minimal log discrepancy of (X ∋ x,B) that is a Kollár component of X ∋ x. If B 6= 0 or X ∋ x is

On minimal log discrepancies
An explanation to the boundness of minimal log discrepancies conjectured by V.V. Shokurov would be that the minimal log discrepancies of a variety in its closed points define a lower semi-continuous

We show the semi-continuity property of minimal log discrepancies for varieties which have a crepant resolution in the category of Deligne-Mumford stacks. Using this property, we also prove the

Jet schemes and singularities
We give a self-contained presentation of the basic results on jet schemes of singular varieties. Applications are given to invariants of singularities, such as minimal log discrepancies. We simplify
Finite determination conjecture for Mather–Jacobian minimal log discrepancies and its applications
We study singularities in arbitrary characteristic. We propose finite determination conjecture for Mather–Jacobian minimal log discrepancies in terms of jet schemes of a singularity. The conjecture
Algebraization and Tannaka duality
Our goal in this paper is to identify certain naturally occurring colimits of schemes and algebraic spaces. To do so, we use (and prove) some new Tannaka duality theorems for maps of algebraic spaces.
Singularities in arbitrary characteristic via jet schemes
This paper summarizes the results at the present moment about singularities with respect to the Mather-Jacobian log discrepancies over algebraically closed field of arbitrary characteristic. The
Jet schemes, log discrepancies and inversion of adjunction
Singularities play a key role in the Minimal Model Program. In this paper we show how some of the open problems in this area can be approached using jet schemes. Let (X, Y ) be a pair, where X is a
