(Wiley, 2020)In this paper, we study a new class of functions, which we call (omega, c)-asymptotically periodic functions. This collection includes asymptotically periodic, asymptotically antiperiodic, asymptotically Bloch-periodic, ...

(RESILIENCE ALLIANCE, 2008-12)The biocultural conservation and research initiative of Omora Ethnobotanical Park and the UNESCO Cape Horn Biosphere Reserve was born in a remote part of South America and has rapidly expanded to attain regional, national, ...
-
(1997)We introduce the notion of (h,k) manifolds and give conditions under which the property of being a manifold with asymptotic phase holds. These conditions allow the construction of a transformation of the variational equation ...
-
(Elsevier Science Ltd, 1999)Hartman's linearization theorem for ordinary differential equations states that a 1:1 correspondence exists between solutions of a linear autonomous system and those of a perturbed system as long as the perturbation term ...
-
(Springer, 2016)To every abelian subvariety of a principally polarized abelian variety (A,L) we canonically associate a numerical class in the Néron–Severi group of A.We prove that these classes are characterized by their intersection ...
-
(Walter de Gruyter and Co., 2003)In this article we study a Rankin-Selberg convolution of two complex variables attached to Siegel modular forms of degree 2. We establish its basic analytic properties, find its singular curves and compute some of its ...
-
(2009)We define a twisted two complex variables Rankin-Selberg convolution of Siegel cusp forms of degree 2. We find its group of functional equations and prove its analytic continuation to ℂ2. As an application we obtain a ...
-
(2004)In this article we study a Rankin-Selberg convolution of n complex variables for pairs of degree n Siegel cusp forms. We establish its analytic continuation to ℂn, determine its functional equations and find its singular ...

(Universidad de Chile, 2019-06-25)En esta tesis presentamos dos modelos de fenómenos cuánticos donde estudiamos comportamientos resonantes. El primero corresponde a una partícula atrapada por una barrera defi nida por una Delta de Dirac en el semieje ...
-
(Universidad de Chile, 2009)En la tesis consideramos acciones de grupos en r,ariedades unidimensionales. En e1 primer capÍtu1o probamos que 1a entropía de Ia acción de un grupo en el círculo, por difeomorfismos de clase C2, es igual a la entropía ...
-
(1997)We use Humbert's reduction theory to introduce an obstruction for the unimodularity of minimal vectors of positive definite quadratic forms over totally real number fields. Using this obstruction we obtain an inequality ...
-
(London Mathematical Society, 2014)Every Jacobi cusp form of weight k and index m over SL2(Z) Z2 is in correspondence with 2m Dirichlet series constructed with its Fourier coefficients. The standard way to get from one to the other is by a variation of ...
-
(Walter de Gruyter GMBH, 2022)In this article, we study compact Riemann surfaces of genus g with an automorphism of prime order g C 1. The main result provides a classification of such surfaces. In addition, we give a description of them as algebraic ...
-
(2007)We extend the concept of commutative nilalgebras to commutative algebras which are not power associative. We shall study commutative algebras A over fields of characteristic ≠ 2, 3 which satisfy the identities x(x(xx)) = ...
-
(IOP PUBLISHING, 2015)Upper main-sequence stars, white dwarfs, and neutron stars are known to possess stable, large-scale magnetic fields. Numerical works have confirmed that stable magnetohydrodynamic equilibria can exist in non-barotropic, ...
-
(World Scientific Publishing Co. Pte Ltd, 2008)We study the variety of algebras A over a field of characteristic ≠ 2, 3, 5 satisfying the identities xy=yx and β ((xx)y)x-((yx)x)x + γ ((xx)x)y-((yx)x)x=0, where β, γ are scalars. We do not assume power-associativity. We ...
-
(Elsevier, 2016)The type and several invariant subspaces related to the upper annihilating series of finite-dimensional nilpotent evolution algebras are introduced. These invariants can be easily computed from any natural basis. Some ...
-
(Academic Press Inc., 2018)© 2018 Elsevier Inc. We apply the theory of Bruhat–Tits trees to the study of optimal embeddings from orders of rank two and three to quaternion algebras. Specifically, we determine how many conjugacy classes of global ...
-
(2007)The existence of idempotent elements in plenary train algebras of rank greater than 3, is an open problem to be solved. J. Carlos Gutierrez's results on plenary train algebras in Gutierrez (2000) are based on the underlying ...
