Self-similar blow-up solutions for the supercritical parabolic Hardy-Hénon equation

Razvan Gabriel Iagar, Ana I. Muñoz, Ariel Sánchez

We classify the self-similar solutions presenting finite time blow-up to the parabolic Hardy-Hénon equation $$ \partial_tu=Δu+|x|^σu^p, \quad (x,t)\in\mathbb{R}^N\times(0,\infty),…

Generalized informational functionals and new monotone measures of statistical complexity

Razvan Gabriel Iagar, David Puertas-Centeno

In this paper we introduce a biparametric family of transformations which can be seen as an extension of the so-called up and down transformations. This new class of transformation…

Through and beyond moments, entropies and Fisher information measures: new informational functionals and inequalities

Razvan Gabriel Iagar, David Puertas-Centeno

We introduce new classes of informational functionals, called \emph{upper moments}, respectively \emph{down-Fisher measures}, obtained by applying classical functionals such as …

A new pair of transformations and applications to generalized informational inequalities and Hausdorff moment problem

Razvan Gabriel Iagar, David Puertas-Centeno

We introduce a pair of transformations, which are mutually inverse, acting on rather general classes of probability densities in R. These transformations have the property of inter…
