Completions of paratopological groups and bounded sets
Springer Verlag (2017)In this paper we consider two questions in the realm of paratopological groups: When does multiplication on a given Tychonoff paratopological group H admit an extension to continuous multiplication on the Dieudonné ... -
Composition operators on the Bloch space of the unit ball of a Hilbert space
Duke University Press (2017)Every analytic self-map of the unit ball of a Hilbert space induces a bounded composition operator on the space of Bloch functions. Necessary and sufficient conditions for compactness of such composition operators are ... -
Compositions of pseudo-symmetric integrators with complex coefficients for the numerical integration of differential equations
Elsevier (2020-05-29)In this paper, we are concerned with the construction and analysis of a new class of methods obtained as double jump compositions with complex coefficients and projection on the real axis. It is shown in particular that ... -

Computational tools to construct semi-analytical planetary theories
Taylor & Francis (2008)The main aim of this paper is the construction of a set of computational tools in order to improve the management of large expansions used in celestial mechanics. This package involves an iterative algorithm to develop the ... -
Computational uncertainty quantification for random non-autonomous second order linear differential equations via adapted gPC: a comparative case study with random Fröbenius method and Monte Carlo simulation
De Gruyter (2018-12)This paper presents a methodology to quantify computationally the uncertainty in a class of differential equations often met in Mathematical Physics, namely random non-autonomous second-order linear differential equations, ... -
Computational uncertainty quantification for random time‐discrete epidemiological models using adaptive gPC
John Wiley & Sons, Ltd. (2018-10-22)Population dynamics models consisting of nonlinear difference equations allow us to get a better understanding of theprocesses involved in epidemiology. Usually, these mathematical models are studied under a deterministic ... -
Computing the Matrix Exponential with an Optimized Taylor Polynomial Approximation
MDPI (2019)A new way to compute the Taylor polynomial of a matrix exponential is presented which reduces the number of matrix multiplications in comparison with the de-facto standard Paterson-Stockmeyer method for polynomial ... -

Conditions for Sylow 2-subgroups of the Fixed Point Subgroup Implying Solubility
Cambridge University Press (2018)Let A and G be finite groups and suppose that A acts via automorphisms on G with (|A|, |G|) = 1. We study how certain conditions on the Sylow 2-subgroups of the fixed point subgroup of the action, CG(A), may imply the ... -
Conformal type of ends of revolution in space forms of constant sectional curvature
Springer (2016-03)In this paper, we consider the conformal type (parabolicity or non-parabolicity) of complete ends of revolution immersed in simply connected space forms of constant sectional curvature. We show that any complete end of ... -
Conjugacy classes and union of cosets of normal subgroups
Springer Nature (2023)Let G be a finite group, N a normal subgroup of G and K a conjugacy class of G. We prove that if K∪K−1 is union of cosets of N, then N is soluble, K is a real-imaginary class, that is, every irreducible character of G takes ... -

Conjugacy classes contained in normal subgroups: an overview
University of Isfahan (2017)We survey known results concerning how the conjugacy classes contained in a normal subgroup and their sizes exert an in uence on the normal structure of a nite group. The approach is mainly presented in the framework ... -
Conservation Laws in Biochemical Reaction Networks
Society for Industrial and Applied Mathematics (2017)We study the existence of linear and non-linear conservation laws in biochemical reaction networks with mass-action kinetics. It is straightforward to compute the linear conservation laws as they are related to the left ... -
