Completeness of constructible norms
Juan Rafael Acosta-Portilla, Armando Sánchez-Nungaray, Gerardo Ramos-Vázquez +1
In the present work we study for a given Banach space the quotient of the family of equivalent norms modulus the collinearity relationship and prove that under a Banach-Mazur type…

Toeplitz operators and group-moment coordinates for quasi-elliptic and quasi-hyperbolic symbols
Raul Quiroga-Barranco, Armando Sanchez-Nungaray
For the -dimensional unit ball and its Siegel unbounded realization, we consider Toeplitz operators acting on weighted Bergman spaces with symbols invariant…

Moment maps of Abelian groups and commuting Toeplitz operators acting on the unit ball
Raul Quiroga-Barranco, Armando Sanchez-Nungaray
We prove that to every connected Abelian subgroup of the biholomorphisms of the unit ball we can associate a set of bounded symbols whose corresponding Toeplitz…
