Electrostatic theory of rectangular waveguides filled with anisotropic media

open access: yesScientific Reports, 2021
The electrostatic (or, in a better word, quasi-electrostatic) theory of waves propagation in a long, rectangular waveguide having perfect electric conductor walls that filled with an anisotropic medium (here, a medium of nanowire-based hyperbolic ...

A note on the higher Atiyah-Patodi-Singer index theorem on Galois coverings [PDF]

open access: yes, 2015
Let $\Gamma$ be a finitely generated discrete group satisfying the rapid decay condition. We give a new proof of the higher Atiyah-Patodi-Singer theorem on a Galois $\Gamma$-coverings, thus providing an explicit formula for the higher index associated to

Positive Psychology Broadens Readers’ Attentional Scope During L2 Reading: Evidence From Eye Movements

open access: yesFrontiers in Psychology, 2019
While positive psychology has drawn increasing interests among researchers in the second language (L2) acquisition literature recently, little is known with respect to the relationship between positive psychology and mental processes during L2 reading ...

Criterion for Cannon's Conjecture [PDF]

open access: yes, 2012
The Cannon Conjecture from the geometric group theory asserts that a word hyperbolic group that acts effectively on its boundary, and whose boundary is homeomorphic to the 2-sphere, is isomorphic to a Kleinian group.

The Waring problem for Lie groups and Chevalley groups [PDF]

open access: yes, 2014
The classical Waring problem deals with expressing every natural number as a sum of g(k) k-th powers. Similar problems were recently studied in group theory, where we aim to present group elements as short products of values of a given non-trivial word w.

Continued fractions related to a group of linear fractional transformations

open access: yesOpen Mathematics, 2023
There are strong relations between the theory of continued fractions and groups of linear fractional transformations. We consider the group G3,3{G}_{3,3} generated by the linear fractional transformations a=1−1∕za=1-1/z and b=z+2b=z+2.

Controlled coarse homology and isoperimetric inequalities [PDF]

open access: yes, 2010
We study a coarse homology theory with prescribed growth conditions. For a finitely generated group G with the word length metric this homology theory turns out to be related to amenability of G.

Comparison of Different Coordination Strategies for the RoboCupRescue Simulation [PDF]

open access: yesAdvanced Robotics, 2004
Evolutionary techniques are one of the most successful paradigms in the field of optimization. In this paper we present a new approach, named GAEDA, which is a new hybrid algorithm based on genetic and estimation of distribution algorithms. The original objective is to get benefits from both approaches.
