Semilinear fractional stochastic differential equations driven by a $\gamma$ -Hölder continuous signal with $\gamma>2 / 3$
In this paper, we use the techniques of fractional calculus to study the existence of a unique solution to semilinear fractional differential equation driven by a $\gamma$ -Hölder continuous function $\theta$ with $\gamma ...
Plattenbauten: touching rectangles in space
Planar bipartite graphs can be represented as touching graphs of horizontal and vertical segments in $\mathbb{R}^2$. We study a generalization in space: touching graphs of axis-aligned rectangles in $\mathbb{R}^3$, and ...
Uniformization of triangle modular curves
In the present article, we determine explicit uniformizations of modular curves attached to triangle Fuchsian groups with cusps. Their Hauptmoduln are obtained by integration of non-linear differential equations of the ...
The Boundary Harnack Principle for Nonlocal Elliptic Operators in Non-divergence Form
We prove a boundary Harnack inequality for nonlocal elliptic operators $L$ in non-divergence form with bounded measurable coefficients. Namely, our main result establishes that if $L u_1=$ $L u_2=0$ in $\Omega \cap B_1, ...
On the use of the descriptive variable for enhancing the aggregation of crowdsourced labels
The use of crowdsourcing for annotating data has become a popular and cheap alternative to expert labelling. As a consequence, an aggregation task is required to combine the different labels provided and agree on a single ...
Global dynamics of the real secant method
We investigate the root finding algorithm given by the secant method applied to a real polynomial $p$ as a discrete dynamical system defined on $\mathbb{R}^{2}$ . We study the shape and distribution of the basins of ...
Resolución del problema de Cauchy relativo a una clase de ecuaciones en derivadas parciales de tercer orden cuasi-lineales y de tipo hiperbólico. (I)
Este trabajo complementa otros tres anteriores nuestros ([lJ, [2] y [3J), y en él se plantea y resuelve localmente el Problema de CAUCHY relativo a la ecuación en derivadas parciales de 3.er orden, cuasi-lineal y de ...
Linear bornologies and associated topologies
This paper is basically devoted to the study of the relation between a linear homology and the associated M-closure topology, introduced in (3) and (18). This topology is invariant in translations and dilations, and it has ...
Some results in representable Banach spaces
Some results are presented, concerning a class of Banach spaces introduced by G. Godefroy and M. Talagrand, the representable Banach spaces. The main aspects considered here are the stability in forming tensor products, ...
Les contribucions de Poincaré a l'aritmètica
Les recerques de Poincaré sobre grups fuchsians, funcions automorfes, etc., estan lligades a les de l'escola alemanya del seu temps. La influència d'aquests temes en teoria de nombres ha estat creixent en el decurs dels ...
Solving $ax^p+by^p=cz^p$ with $abc$ containing an arbitrary number of prime factors.
In this paper we prove new cases of the asymptotic Fermatequation with coefficients. This is done by solving some remarkable S-unit equations and applying a method of Frey-Kraus-Mazur.
A characterization of bilinear forms on the dirichlet space
Arcozzi, Rochberg, Sawyer and Wick obtained a characterization of the holomorphic functions $b$ such that the Hankel type bilinear form $T_{b}(f,g)=\int_{\mathbb{D}}(I+R)(f,g)(z)\overline{(I+R)b(z)}dv (z) $ is bounded on ...
Aplicación del método de Dedekind a un cuerpo ordenado no arquimediano
A partir del cuerpo de los números racionales, hay dos métodos históricos de introducción de los números reales : el método de DEDEKIKD mediante cortaduras, y el de CANTOR mediante sucesiones de C..,.rcHY. Estos dos ...
Poncelet a la presó de Saratov
Poncelet va ser un militar francès que va formar part de les tropes napoleòniques que van perdre la batalla de Krasni a la campanya de Rússia. Durant el seu captiveri a la presó de Saratov, basant-se en el record de les ...
Finitely generated ideals in the Nevanlinna class.
In this paper we investigate finitely generated ideals in the Nevanlinna class. We prove analogues to some known results for the algebra of bounded analytic functions $H^{\infty}$. We also show that, in contrast to the ...
The Calderón problem for nonlocal Schrödinger equations with homogeneous, directionally antilocal principal symbols
In this article we consider direct and inverse problems for $\alpha$-stable, elliptic nonlocal operators whose kernels are possibly only supported on cones and which satisfy the structural condition of directional antilocality ...
Multi-Objective Reinforcement Learning for Designing Ethical Environments
AI research is being challenged with ensuring that autonomous agents learn to behave ethically, namely in alignment with moral values. A common approach, founded on the exploitation of Reinforcement Learning techniques, ...
Expansion of the density: a Wiener-chaos approach
We prove a Taylor expansion of the density pε(y) of a Wiener functional Fε with Wiener-chaos decomposition Fε=y+∑∞n=1εnIn(fn), ε∈(0,1]. Using Malliavin calculus, a precise description of the coefficients in the development ...
On the structure of the canonical module of the Rees algebra and the associated graded ring of and ideal
In this note we give the description of a morphism related with the structure of the canonocal module of the Rees algebra R(I) of an ideal I in a local ring . As an application we obtain Ikeda's criteria for the Gorensteinness ...
