In this note we investigate some basic properties of the level sets of functions which are homogeneous with respect to nonisotropic dilations. In particular we obtain a formula for the volume of the level sets in terms of ...

An analysis of iterated deferred correction based on various classes of implicit Runge-Kutta formulae is given. Out of different possibilities considered, it is shown that those based purely on Lobatto formulae have the ...

We prove a mean value formula for weak solutions of div(|y| agradu) = 0 in Rn+1 = {(x, y) : x ∈ Rn, y ∈ R}, −1 < a < 1, and balls centered at points of the form (x, 0). We obtain an explicit nonlocal kernel for the mean ...

En esta tesis abordamos dos problemas naturales del análisis de soluciones de fenómenos de transporte anómalo. El primero es el de existencia de soluciones para un problema de Cauchy asociado a CATC (Caminos Aleatorios a ...

Introduction: Although the levels of low-density lipoprotein (LDL-C) should ideally be determined by beta quantification or enzymatic methods, there are limitations in developing countries. The goal of this study is to ...

Aim: The aim of the present preliminary study was to determine sugar concentration in infant follow-on formulas most widely consumed in Peru. Materials and methods: In this descriptive and observational study, the sample ...
