On analytic families of conformal maps
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas - Sociedad Colombiana de Matemáticas, 2017-01-01)
Let Λ be a domain in C and let fλ(z) = z + a0(λ) + a1(λ)z −1 + ... be meromorphic in D∗ := {z ∈ C : |z| 1} ∪ {∞}. We assume that fλ(z) is holomorphic in λ ∈ Λ for fixed z.The main theorem states: Let Λ0 be a subdomain of ...
Compensated convex transforms and geometric singularity\ extraction from semiconvex functions补偿凸变换与半凸函数的几何奇点提取
(Science China Press, 2016-04)
The upper and lower compensated convex transforms are `tight' one-sided approximations for a given function. We apply these transforms to the extraction of fine geometric singularities from general semiconvex/semiconcave ...
Existence of a positive solution to a semilinear equation involving pucci's operator in a convex domain
(2004)
In this article we prove existence of positive solutions for the nonlinear elliptic equation ℳ λ,Λ + (D 2 u)-γu+f(u)=0inΩ,u=0on∂Ω, where ℳ λ,Λ + denote Pucci’s extremal operator with parameters 0<λ≤Λ and Ω is convex smooth ...
Nonmesonic weak decay of Λ-hypernuclei within independent-particle shell-model
(2010-08-27)
After a short introduction to the nonmesonic weak decay (NMWD) ΛN→nN of Λ-hypernuclei we discuss the long-standing puzzle on the ratio Γn/Γp, and some recent experimental evidences that signalized towards its final solution. ...
Interior bubbling solutions for the critical Lin-Ni-Takagi problem in dimension 3
(Springer New York LLC, 2019)
We consider the problem of finding positive solutions of the problem Δu − λu + u 5 = 0 in a bounded, smooth domain Ω in ℝ 3 , under zero Neumann boundary conditions. Here λ is a positive number. We analyze the role of ...
Medidas difusas e integrales difusas
This is a study of fuzzy measures and fuzzy inte-grals; it presents some of the phenomena wherethey are used. It exposes how the concept of fuzzymeasure is introduced and from it, the notion offuzzy integral is presented. ...
