Isometric embeddings of snowflakes into finite-dimensional Banach spaces

2016

We consider a general notion of snowflake of a metric space by composing the distance by a nontrivial concave function. We prove that a snowflake of a metric space $X$ isometrically embeds into some finite-dimensional normed space if and only if $X$ is finite. In the case of power functions we give a uniform bound on the cardinality of $X$ depending only on the power exponent and the dimension of the vector space.

Duality of moduli in regular toroidal metric spaces

2020

We generalize a result of Freedman and He [4, Theorem 2.5], concerning the duality of moduli and capacities in solid tori, to sufficiently regular metric spaces. This is a continuation of the work of the author and Rajala [12] on the corresponding duality in condensers. peerReviewed

On the existence of at least a solution for functional integral equations via measure of noncompactness

2017

In this article, we use fixed-point methods and measure of noncompactness theory to focus on the problem of establishing the existence of at least a solution for the following functional integral equation ¶ \[u(t)=g(t,u(t))+\int_{0}^{t}G(t,s,u(s))\,ds,\quad t\in{[0,+\infty[},\] in the space of all bounded and continuous real functions on $\mathbb{R}_{+}$ , under suitable assumptions on $g$ and $G$ . Also, we establish an extension of Darbo’s fixed-point theorem and discuss some consequences.

Quantization of Poisson Lie Groups and Applications

1996

LetG be a connected Poisson-Lie group. We discuss aspects of the question of Drinfel'd:can G be quantized? and give some answers. WhenG is semisimple (a case where the answer isyes), we introduce quantizable Poisson subalgebras ofC ∞(G), related to harmonic analysis onG; they are a generalization of F.R.T. models of quantum groups, and provide new examples of quantized Poisson algebras.

Splenic Littoral Cell Hemangioendothelioma in a Patient With Crohn's Disease Previously Treated With Immunomodulators and Anti-TNF Agents: A Rare Tum…

2011

Th e risk of malignancy in Crohn ’ s disease (CD) has been well described. Moreover, immunomodulators, uch as azathioprine (AZA) and 6-mercaptopurine (6-MP), and biological agents, such as infl iximab and adalimumab, may promote carcinogenesis ( 1 – 3 ). Splenic littoral cell tumors are recently described tumors of vascular origin composed of endothelial cells, with typical microscopic and immunohistochemical features of splenic sinus lining cells ( 4 ). Clinical findings are not specific, and outcome is unpredictable but usually benign, although a few cases with a malignant behavior have been reported ( 5,6 ). We report a 58-year-old Caucasian man with a long history of ileocolonic CD.

Non-autonomous rough semilinear PDEs and the multiplicative Sewing Lemma

2021

We investigate existence, uniqueness and regularity for local solutions of rough parabolic equations with subcritical noise of the form $du_t- L_tu_tdt= N(u_t)dt + \sum_{i = 1}^dF_i(u_t)d\mathbf X^i_t$ where $(L_t)_{t\in[0,T]}$ is a time-dependent family of unbounded operators acting on some scale of Banach spaces, while $\mathbf X\equiv(X,\mathbb X)$ is a two-step (non-necessarily geometric) rough path of H\"older regularity $\gamma >1/3.$ Besides dealing with non-autonomous evolution equations, our results also allow for unbounded operations in the noise term (up to some critical loss of regularity depending on that of the rough path $\mathbf X$). As a technical tool, we introduce a versi…

Declaration of will of persons with disabilities in the general theory of legal act and the new perspective based on supports. A study of peruvian law

2021

Indexado en Redib La Convención sobre los Derechos de las Personas con Discapacidad ha supuesto, en términos generales, un replanteamiento de la idea de autonomía de la voluntad al reconocer plena capacidad jurídica en todo sujeto con independencia de su discapacidad. Esta nueva realidad viene a modificar el modo de conceptuar e interpretar la declaración de voluntad en la teoría general del acto jurídico, y muy en especial, cuando la capacidad natural de conocer y querer puede venir naturalmente limitada por una discapacidad psíquica o por un estado de coma. La formación interna de la voluntad y su manifestación se vuelve un asunto complejo, sobre todo cuando los apoyos podrían no ser gara…

Futuro profesional de los menores y ejercicio de la patria potestad

2021

The personal decision about the professional future of the minor, constitutes an aspect of the development of his free personality, and, like every decision that affects him, it must be adopted considering the principle of the best interests of the child. The parents, in the exercise of parental authority, have the legal representation of their minor children, except for the acts related to the personality rights, which can be carried out by the minor child himself if he is mature enough. When personality rights and economic rights converge, it is necessary to determine the role the parents play, which in the end will always have to be the protection and respect for their children?s rights.
