Artistic proposals of visual arts of Ecuador since the second half of the twentieth century to the present

This article is the result of a research that analyzes the most important artistic proposals of Visual Arts in Ecuador, since the second half of the twentieth century to the present. Through literature review and data collection held in the city of Guayaquil, we could determine their influence and impact on the circuit of contemporary art. The instruments used for data collection were depth interviews that were done to experts in the field. Like surveys of attendees at different artistic events (exhibitions, permanent exhibitions, seminars), allowed to establish the social interests of those proposals. The methodology was mixed approach, quantitative and qualitative data were used.

On the simplicial cohomology of Banach operator algebras

We investigate the simplicial cohomology of certain Banach operator algebras. The two main examples considered are the Banach algebra of all bounded operators on a Banach space and its ideal of approximable operators. Sufficient conditions will be given forcing Banach algebras of this kind to be simplicially trivial.

1-amenability of A(X) for Banach spaces with 1-unconditional bases

The main result of the note is a characterization of 1-amenability of Banach algebras of approximable operators for a class of Banach spaces with 1-unconditional bases in terms of a new basis property. It is also shown that amenability and symmetric amenability are equivalent concepts for Banach algebras of approximable operators, and that a type of Banach space that was long suspected to lack property A has in fact the property. Some further ideas on the problem of whether or not amenability (in this setting) implies property A are discussed.
