Abstract

DRAGOMIR, S. S.; BOLDEA, M. V  and  MEGAN, M. Inequalities for Chebyshev Functional in Banach Algebras. Cubo [online]. 2017, vol.19, n.1, pp.53-77. ISSN 0719-0646.  http://dx.doi.org/10.4067/S0719-06462017000100004.

Usando algunas identidades para sumas dobles, encontramos algunas nuevas desigualdades para el funcional de Chebyshev en álgebras de Banach. También entregamos algunos ejemplos para las funciones exponencial y resolvente en álgebras de Banach.

Keywords : Banach algebras; Power series; Exponential function; Resolvent function; Norm inequalities.
