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 and union of cosets of normal subgroups
Springer (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 ... -
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 ... -
Constructive approximation of continuous interval- valued functions
Taylor & Francis (2021-11-28)In this paper we present a Stone-Weierstrass type result in the context of continuous interval-valued functions defined on a compact Hausdorff space. We also provide a Jackson type approximation result involving the modulus ... -
Constructive approximation of level continuous fuzzy functions 1
IOS (2019-06)We consider the space of continuous functions defined between a locally compact Hausdorff space and the space of fuzzy numbers endowed with the level convergence topology. We obtain a Stone-Weierstrass type theorem for ... -
Consumer behaviour and environmental education in the field of waste electrical and electronic toys: A Spanish case study
Elsevier (2015-02)This paper reports on a project focused on obtaining the current consumption and disposal habits of electrical and electronic toys from a survey aimed at parents of children of nine pre- and primary schools. In addition, ... -
Consumer practices regarding the purchase, use, willingness to repair, and disposal of small electric and electronic equipment: A Spanish survey on kettles
Wiley (2023)Repair is one of the main strategies to extend the lifetime of products in the circular economy framework. With the aim of identifying current consumer practices toward the purchase, use, and end of life of electric and ... -
Contextual contact tracing based on stochastic compartment modeling and spatial risk assessment
Springer (2021-10-26)The current situation of COVID-19 highlights the paramount importance of infectious disease surveillance, which necessitates early monitoring for effective response. Policymakers are interested in data insights identifying ... -
Continuous Selections and Extremally Disconnected Spaces
MDPI (2023)This paper deals with extremally disconnected spaces and extremally disconnected Pspaces. A space X is said to be extremally disconnected if, for every open subset V of X, the closure of V in X is also an open set. P-spaces ... -
Contributions to the Bohr topology by W.W. Comfort
Elsevier (2019)The important rôle that W. W. Comfort played in the study of the Bohr topology is described. -
Convergence analysis of high-order commutator-free quasi-Magnus exponential integrators for nonautonomous linear evolution equations of parabolic type
Oxford University Press (2018-04)The main objective of this work is to provide a stability and error analysis of high-order commutator-free quasi-Magnus (CFQM) exponential integrators. These time integration methods for nonautonomous linear evolution ... -
Convergence analysis of high-order commutator-free quasi-Magnus exponential integrators for nonautonomous linear Schrödinger equations
Oxford University Press (2020-03-02)This work is devoted to the derivation of a convergence result for high-order commutator-free quasi-Magnus (CFQM) exponential integrators applied to nonautonomous linear Schrödinger equations; a detailed stability and local ... -
Coprime action and arithmetical conditions on invariant conjugacy classes
Springer Verlag (2015-12)Let A and G be finite groups and suppose that A acts coprimely on G via automorphisms. We show that if 4 divides no A-invariant conjugacy class size of G, then G is solvable. We also characterize the A-invariant structure ... -

Corrigendum to: “A coprime action version of a solubility criterion of Deskins”
Springer Verlag (2020-01-14)In this Corrigendum we correct a missed case in the statement of Theorem 2.4 and a subsequent mistake in the proof of the main result in “A coprime action version of a solubility criterion of Deskins”, Monatsh. Math. ... -
Cosets of normal subgroups and powers of conjugacy classes
Wiley (2021-08-03)Let 𝐺 be a finite group and let𝐾 = 𝑥𝐺 be the conjugacy class of an element 𝑥 of 𝐺. In this paper, it is proved that if 𝑁 is a normal subgroup of 𝐺 such that the coset 𝑥𝑁 is the union of 𝐾 and 𝐾−1 (the conjugacy ... -
Could Plant Hormones Provide a Reliable Tool for Early Detection of Rhynchophorus ferrugineus (Coleóptera: Curculionidae) Infested Palms?
Entomological Research Society (2019-03)Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) is one of the most important pest of palms worldwide. A serious management problem is the difficulty of detecting early infestation stages, which is critical ... -
Covariance functions for multivariate Gaussian fields evolving temporally over planet earth
Springer-Verlag GmbH Germany, part of Springer Nature (2019-07-18)The construction of valid and flexible cross-covariance functions is a fundamental task for modeling multivariate space– time data arising from, e.g., climatological and oceanographical phenomena. Indeed, a suitable ... -
COVID-19 transmission risk in Surabaya and Sidoarjo: an inhomogeneous marked Poisson point process approach
