We give a simple geometric characterization of isospectral orbifolds covered by spheres, complex projective spaces and the quaternion projective line having cyclic fundamental group. The differential operators considered ...

The objective of this work is to study the techniques developed in the theory of blocks for finite groups and then, using the machinery of profinite groups and results from the modular representation theory of profinite ...

Stable immobilization and homogenous distribution of ZnO nanostructures on solid substrates can play a fundamental role in developing nanostructured biosensing devices. In this work we studied how phosphonic acid-terminated ...

The essential role of a well-defined hydrogen-bond network in achieving chemically reversible multiproton translocations triggered by one-electron electrochemical oxidation/reduction is investigated by using pyridylbenzi ...

Cyclic and linear nucleotides are key elements of the signal transduction networks linking perception of the environment to specific cellular behavior of prokaryotes. These molecular mechanisms are particularly important ...

Uno de los resultados más importantes que se ven en el curso de Álgebra Abstracta es la clasificación de grupos abelianos finitos: se sabe que todo grupo abeliano finito es isomorfo a la suma directa de grupos cíclicos ...
