c-Normality and coprime action in finite groups
Springer (2023-10-31)A subgroup H of a finite group G is called c-normal if there exists a normal subgroup N in G such that G = HN and , the largest normal subgroup of G contained in H. c-Normality is a weaker form of normality, introduced by ... -
Can interactions among predators alter the natural regulation of an herbivore in a climate change scenario? The case of Tetranychus urticae and its predators in citrus
Springer (2019-06)Climate change can dramatically affect the food web configuration of arthropod communities through its effects on species interactions. We have studied whether these effects could alter the probability of local extinction ... -
Capturing spatial dependence of COVID-19 case counts with cellphone mobility data
Elsevier (2022)Spatial dependence is usually introduced into spatial models using some measure of physical proximity. When analysing COVID-19 case counts, this makes sense as regions that are close together are more likely to have more ...

Challenges Regarding Scientific Transcription in Virtual Office Hours
MDPI (2021-03-24)Mathematics teachers face great difficulties during virtual communication with their students, mainly because scientific and technical subjects use a great many mathematical symbols, abstract objects and a wide variety ...

Chaos in hyperspaces of nonautonomous discrete systems
Elsevier (2017)We study the interaction of some dynamical properties of a nonautonomous discrete dynamical system (X, f∞) and its induced nonautonomous discrete dynamical system (K(X),f∞¯), where K(X) is the hyperspace of non-empty compact ...

Chaos in King's iterative family
Elsevier (2013-08)In this paper, the dynamics of King’s family of iterative schemes for solving nonlinear equations is studied. The parameter spaces are presented, showing the complexity of the family. The analysis of the parameter space ...

Chaotic semigroups from second order partial differential equations
Elsevier (2017-12)We give general conditions on given parameters to ensure Devaney and distributional chaos for the solution Co-semigroup corresponding to a class of second-order partial differential equations. We also provide a critical ...

Characterizing group C*-algebras through their unitary groups: the Abelian case
Walter de Gruyter (2010-07)We study to what extent group C*-algebras are characterized by their unitary groups. A complete characterization of which Abelian group C*-algebras have isomorphic unitary groups is obtained. We compare these results with ...

Child t-shirt size data set from 3D body scanner anthropometric measurements and a questionnaire
Elsevier (2017-04)A dataset of a fit assessment study in children is presented. Anthropometric measurements of 113 children were obtained using a 3D body scanner. Children tested a t-shirt of different sizes and a different model for boys ...

Class sizes of prime-power orden p'-elements and normal subgroups
Springer (2014-06)We prove an extension of the renowned Itô’s theorem on groups having two class sizes in three different directions at the same time: normal subgroups, p' -elements and prime- power order elements. Let N be a normal subgroup ...

Classification of Events Using Local Pair Correlation Functions for Spatial Point Patterns
American Statistical Association (2021-05-12)Spatial point pattern analysis usually concerns identifying features in an observation window where there is also noise. This identification traditionally begins with studying the second-order properties of the point ...
-
Clustering constrained on linear networks
Springer (2023)An unsupervised classification method for point events occurring on a geometric network is proposed. The idea relies on the distributional flexibility and practicality of random partition models to discover the clustering ...

Cofactors and equilibria for polynomial vector fields
Cambridge University Press (2014)We present a relationship between the existence of equilibrium points of differential systems and the cofactors of the invariant algebraic curves and the exponential factors of the system

Combining Classification and User-Based Collaborative Filtering for Matching Footwear Size
MDPI (2021)Size mismatch is a serious problem in online footwear purchase because size mismatch implies an almost sure return. Not only foot measurements are important in selecting a size, but also user preference. This is the ...

Comparison theory of Lorentzian distance with applications to spacelike hypersurfaces
American Institute of Physics (2009)In this paper we summarize some comparison results for the Lorentzian distance function in spacetimes, with applications to the study of the geometric analysis of the Lorentzian distance on spacelike hypersurfaces. In ...

Compatibility of soil application of Metarhizium brunneum and cover crops against Ceratitis capitata soil-dwelling stages
Springer (2024-01-13)Fruit fly ground-dwelling stages (late third instar larvae, pupae, and teneral adults) are susceptible to predation from generalist ground-dwelling predators and to infection by entomopathogenic fungi (EPF). The effect of ...

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 ...

Sociedad Mexicana de Investigación y Divulgación de la Educación Matemática A. C. (SOMIDEM, A. C) (2022-12)En este artículo se reporta cómo estudiantes chilenos, de secundaria y universitarios, comprenden el Conjunto Solución de un Sistema de Ecuaciones Lineales de tres ecuaciones y dos incógnitas (CSSEL3x2). El estudio se ...
