Left-induced model structures and diagram categories [PDF]

open access: yes, 2014
We prove existence results a la Jeff Smith for left-induced model category structures, of which the injective model structure on a diagram category is an important example.

Alcove path and Nichols-Woronowicz model of the equivariant $K$-theory of generalized flag varieties [PDF]

open access: yes, 2006
Fomin and Kirillov initiated a line of research into the realization of the cohomology and $K$-theory of generalized flag varieties $G/B$ as commutative subalgebras of certain noncommutative algebras.

Mixed volumes of hypersimplices [PDF]

open access: yes, 2015
In this paper we consider mixed volumes of combinations of hypersimplices. These numbers, called "mixed Eulerian numbers", were first considered by A.

Higher order linear parabolic equations [PDF]

open access: yes, 2012
We first highlight the main differences between second order and higher order linear parabolic equations. Then we survey existing results for the latter, in particular by analyzing the behavior of the convolution kernels.

Schur Positivity and Kirillov-Reshetikhin Modules [PDF]

open access: yes, 2014
In this note, inspired by the proof of the Kirillov-Reshetikhin conjecture, we consider tensor products of Kirillov-Reshetikhin modules of a fixed node and various level.

LAPW vs. LMTO full-potential simulations and anharmonic dynamics of KNbO3

open access: yes, 1998
With the aim to get an insight in the origin of differences in the earlier reported calculation results for KNbO3 and to test the recently proposed implementation of the FP-LMTO method by Methfessel and van Schilfgaarde, we perform a comparative study of

Semiempirical Hartree-Fock calculations for KNbO3

open access: yes, 1996
In applying the semiempirical intermediate neglect of differential overlap (INDO) method based on the Hartree-Fock formalism to a cubic perovskite-based ferroelectric material KNbO3, it was demonstrated that the accuracy of the method is sufficient for ...

Comparison of the Electronic Structures and Energetics of Ferroelectric LiNbO3 and LiTaO3

open access: yes, 1995
This paper explains the origin of the ferroelectric instability in LiNbO3 and LiTaO3 and compares the electronic structures and energetics of the two materials.Comment: 31 pages, 11 Postscript ...

Geometry of rank tests [PDF]

open access: yes, 2006
We study partitions of the symmetric group which have desirable geometric properties. The statistical tests defined by such partitions involve counting all permutations in the equivalence classes. These permutations are the linear extensions of partially

Prospects for terahertz imaging the human skin cancer with the help of gold-nanoparticles-based terahertz-to-infrared converter

open access: yes, 2019
The design is suggested, and possible operation parameters are discussed, of an instrument to inspect a skin cancer tumour in the terahertz (THz) range, transferring the image into the infrared (IR) and making it visible with the help of standard IR ...
