Analytical solutions for macroscopic elastic moduli and thermal expansion coefficient of composite materials containing coated fillers oriented randomly based on the double inclusion method [PDF]

Heliyon
In this study, micromechanical analysis will be performed to derive explicit solutions of the macroscopic elastic moduli and thermal expansion coefficient for composite materials, where spheroidal-coated fillers are oriented randomly in the material ...

Minimal model theory for log surfaces [PDF]

, 2011
We discuss the log minimal model theory for log surfaces. We show that the log minimal model program, the finite generation of log canonical rings, and the log abundance theorem for log surfaces hold true under assumptions weaker than the usual framework

Abundance theorem for semi log canonical surfaces in positive characteristic [PDF]

, 2015
We prove the abundance theorem for semi log canonical surfaces in positive characteristic.Comment: 33 pages. v2: I added Section 3, changed the definition of slc surfaces, and adopted the one of Kollar.

On base point free theorem and Mori dream spaces for log canonical threefolds over the algebraic closure of a finite field

, 2016
The authors and D. Martinelli proved the base point free theorem for big line bundles on a three-dimensional log canonical projective pair defined over the algebraic closure of a finite field.

Behavior of canonical divisors under purely inseparable base changes

, 2016
Let $k$ be an imperfect field. Let $X$ be a regular variety over $k$ and set $Y$ to be the normalization of $(X \times_k k^{1/p^{\infty}})_{{\rm red}}$. In this paper, we show that $K_Y+C=f^*K_X$ for some effective divisor $C$ on $Y$.

On the Abundance Problem for $3$-folds in characteristic $p>5$

, 2018
In this article we prove two cases of the abundance conjecture for $3$-folds in characteristic $p>5$: $(i)$ $(X, \Delta)$ is KLT and $\kappa(X, K_X+\Delta)=1$, and $(ii)$ $(X, 0)$ is KLT, $K_X\equiv 0$ and $X$ is not uniruled.Comment: With an Appendix by

On log del Pezzo surfaces in large characteristic

, 2016
We show that any Kawamata log terminal del Pezzo surface over an algebraically closed field of large characteristic is globally F-regular or it admits a log resolution which is liftable to characteristic zero.
