On solving periodic Riccati equations [PDF]

open access: yes, 2008
Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,

Darboux transformation with dihedral reduction group [PDF]

open access: yes, 2014
We construct the Darboux transformation with Dihedral reduction group for the 2-dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference ...

Periodic rings with finitely generated underlying group

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We study periodic rings that are finitely generated as groups. We prove several structure results. We classify periodic rings that are free of rank at most 2, and also periodic rings R such that R is finitely generated as a group and R/t(R)≃ℤ.

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]

open access: yes, 2015
In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
A group is said to be periodic, if any of its elements is of finite order. A Shunkov group is a group in which any pair of conjugate elements generates Finite subgroup with preservation of this property when passing to factor groups by finite Subgroups ...

The p-period of an infinite group [PDF]

open access: yesPublicacions Matemàtiques, 1992
A group \(\Gamma\) has virtual cohomological dimension \(\operatorname{vcd}n\) if \(\Gamma\) has a subgroup of finite index which has cohomological dimension \(n\). For such groups the Farrell cohomology \(\widehat{H}^ i(\Gamma,-)\) is defined which has formal properties analogous to those of the Tate cohomology for finite groups (in which case \(n=0\))
