Shunkov Groups with Additional Finiteness Conditions, Containing Dihedral Subgroups
Известия Иркутского государственного университета: Серия "Математика"In this paper, Shunkov groups are studied in the context of the well-known question of B. Amberg and L. S. Kazarin about the structure of groups containing direct products of a finite number of dihedral groups.

The State Space Subdivision Filter for Estimation on SE(2)
Sensors, 2021 The SE(2) domain can be used to describe the position and orientation of objects in planar scenarios and is inherently nonlinear due to the periodicity of the angle.

Linear flows on compact, semisimple Lie groups: stability and periodic orbits
Electronic Journal of Qualitative Theory of Differential Equations, 2021 Our first purpose is to study the stability of linear flows on real, connected, compact, semisimple Lie groups. Our second purpose is to study periodic orbits of linear and invariant flows.

Essentially periodic ordered groups
Annals of Pure and Applied Logic, 2000 The authors introduce and study a number of notions extending that of an o-minimal group; i.e., they investigate totally ordered groups with certain restrictions on definable subsets. They also prove a number of interesting results relating the different notions. Some but not all of these notions are closed under elementary equivalence.

Computational Methods for Periodic Systems - An Overview [PDF]
, 2001 We present an up-to-date survey of numerical methods for the analysis and design of linear discrete-time periodic systems. The basic tool is the periodic Schur form and its variants, for which a certain form of numerical stability can be ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Subgroups of paratopological groups and feebly compact groups
Applied General Topology, 2014 It is shown that if all countable subgroups of a semitopological group G are precompact, then G is also precompact and that the closure of an arbitrary subgroup of G is again a subgroup.

An efficient density matrix renormalization group algorithm for chains with periodic boundary condition [PDF]
Papers in Physics, 2016 The Density Matrix Renormalization Group (DMRG) is a state-of-the-art numerical technique for a one dimensional quantum many-body system; but calculating accurate results for a system with Periodic Boundary Condition (PBC) from the conventional DMRG ...
