Δ -weak character amenability of certain Banach algebras

Hamid Sadeghi — 2019

Archivum Mathematicum

In this paper we investigate Δ -weak character amenability of certain Banach algebras such as projective tensor product A ^ B and Lau product A × θ B , where A and B are two arbitrary Banach algebras and θ Δ ( B ) , the character space of B . We also investigate Δ -weak character amenability of abstract Segal algebras and module extension Banach algebras.

Metasearch information fusion using linear programming

Gholam R. AminAli EmrouznejadHamid Sadeghi — 2012

RAIRO - Operations Research - Recherche Opérationnelle

For a specific query merging the returned results from multiple search engines, in the form of a metasearch aggregation, can provide significant improvement in the quality of relevant documents. This paper suggests a minimax linear programming (LP) formulation for fusion of multiple search engines results. The paper proposes a weighting method to include the importance weights of the underlying search engines. This is a two-phase approach which in the first phase a new method for computing the importance...
