We present a unified approach to the study of Radon transforms related to symmetric groups and to general linear groups GLn(q), regarded as q−analogues of the former. In both cases, we define a sequence of generalized ...

We introduce the symmetric-Radon-Nikodým property (sRN pr operty) for finitely generated s-tensor norms β of order n and prove a Lewis type theorem for s-tensor norms with this property. As a consequence, if β is a projective ...

In an effort to promote Compton scatter tomography (CST) as an adequate modality for imaging the inner parts of large objects limited in a half-space of ℝ, we show that the standard CST can be ‘improved’ in some particular ...

In this work, we present conditions to obtain a global-in-time existence of solutions to a class of nonlinear viscous transport equations describing aggregation phenomena in biology with sufficiently small initial data in ...

El radón ocasiona más del 50 % de la dosis total del fondo natural de radiación por año. Está ampliamente demostrada su capacidad para inducir cáncer de pulmón en las personas que están expuestas por largos períodos de ...
