p-Boundedness in paratopological groups
Elsevier (2015-10)We show that bounded subsets of ω-admissible paratopological groups are p -bounded for all p∈ω⁎p∈ω⁎. In other words, they have a similar behavior to bounded subsets of topological groups. We present several new classes ... -
p-Capacity and p-hyperbolicity of submanifolds
Universidad Autónoma de Madrid. Departamento de Matemáticas (2009)We use explicit solutions to a drifted Laplace equation in warped product model spaces as comparison constructions to show $p$-hyperbolicity of a large class of submanifolds for p>2. The condition for $p$-hyperbolicity is ... -
p-divisibility of conjugacy class sizes and normal p-complements
De Gruyter (2015-01)Let N be a normal subgroup of a group G and let p be a prime.We prove that if the p-part of jxGj is a constant for every prime-power order element x 2 N n Z.N /, then N is solvable and has normal p-complement. -
Parabolicity criteria and characterization results for submanifoldsof bounded mean curvature in model manifolds with weights
Elsevier (2020)Let P be a submanifold properly immersed in a rotationally symmetric manifold having a pole and endowed with a weight e h. The aim of this paper is twofold. First, by assuming certain control on the h-mean curvature of ... -
Parabolicity of Invariant Surfaces
Springer (2024-02-22)We present a clear and practical way to characterize the parabolicity of a complete immersed surface that is invariant with respect to a Killing vector field of the ambient space. -
Parabolicity, Brownian Exit Time and Properness of Solitons of the Direct and Inverse Mean Curvature Flow
(2019-10-05)We study some potential theoretic properties of homothetic solitons n of the MCF and the IMCF. Using the analysis of the extrinsic distance function defined on these submanifolds in Rn+m, we observe similarities and ... -
Parameter estimation in non-homogeneous boolean models: an application to plant defense response
International Society for Stereology (2014-09)Many medical and biological problems require to extract information from microscopical images. Boolean models have been extensively used to analyze binary images of random clumps in many scientific fields. In this paper, ... -
Partial and semi-partial statistics of spatial associations for multivariate areal data
Wiley (2020-06-12)The analysis of correlation structures among multivariate spatially aggregated data has become increasingly important and poses substantial challenges. This article concerns the development of partial and semi‐partial ... -
Partial characteristics for marked spatial point processes
Wiley (2019-09)This paper introduces a new class of partial summary characteristics for twotypes of marked planar point processes. We consider purely qualitatively marked spatial point processes and multitype spatial point processes with ... -
PDE triangular Bézier surfaces: Harmonic, biharmonic and isotropic surfaces
Elsevier (2011)We approach surface design by solving second-order and fourth-order Partial Differential Equations (PDEs). We present many methods for designing triangular Bézier PDE surfaces given different sets of prescribed control ... -
Period-doubling bifurcations in the family of Chebyshev–Halley-type methods
Taylor & Francis (2013)The choice of a member of a parametric family of iterative methods is not always easy. The family of Chebyshev–Halley schemes is a good example of it. The analysis of bifurcation points of this family allows us to define ... -
Periodically Correlated Space-Time Autoregressive Hilbertian Processes
Atlantis Press (2021-06)In this paper, we introduce periodically correlated space-time autoregressive processes with values in Hilbert spaces. The existence conditions and the strong law of large numbers are established. Moreover, we present an ... -
Phase portraits of Abel quadratic differential systems of the second kind
Taylor & Francis (2018)We provide normal forms and the global phase portraits on the Poincaré disk of some Abel quadratic differential equations of the second kind. Moreover, we also provide the bifurcation diagrams for these global phase portraits. -
Plant‑feeding may explain why the generalist predator Euseius stipulatus does better on less defended citrus plants but Tetranychus‑specialists Neoseiulus californicus and Phytoseiulus persimilis do not
Springer (2021-01-22)The generalist predator Euseius stipulatus (Athias-Henriot) and the Tetranychidae-specialist predators Neoseiulus californicus (McGregor) and Phytoseiulus persimilis Athias-Henriot play a key role in the regulation of ... -
Poincaré series for curve singularities and its behaviour under projections
Elsevier (2015)Let O be an equicharacteristic reduced complete noetherian local ring of Krull dimension one, and let S be the value semigroup associated with O. The aim of the paper is to investigate the behaviour of the multi-variable ... -
Point Pattern Analysis of Spatial Deformation and Blurring Effects on Exceedances
Springer US (2016-09)Structural characteristics of random field threshold exceedance sets (e.g., size, connectivity, and boundary regularity) are used in practice for definition of different indicators in spatial and spatio-temporal risk ... -
Point process modeling through a mixture of homogeneous and self-exciting processes
Wiley (2024)Self-exciting point processes allow modeling thetemporal location of an event of interest, consideringthe history provided by previously observed events.This family of point processes is commonly used inseveral areas such ... -
Positivity of discrete singular systems and their stability: An LP-based approach
Elsevier (2014-01)In this paper we present an efficient approach to the analysis of discrete positive singular systems. One of our main objectives is to investigate the problem of characterizing positivity of such systems. Previously, this ... -
Powers of conjugacy classes in a finite group
Springer (2019)The aim of this paper is to show how the number of conjugacy classes appearing in the product of classes affect the structure of a finite group. The aim of this paper was to show several results about solvability concerning ... -
Precompact groups and property (T)
Elsevier (2013-08)For a topological group GG, the dual object View the MathML sourceĜ is defined as the set of equivalence classes of irreducible unitary representations of GG equipped with the Fell topology. It is well known that, if GG ...
