Some of the most recent and significant results on homomorphisms and
derivations in Banach algebras, quasi-Banach algebras, C*-algebras,
C*-ternary algebras, non-Archimedean Banach algebras and multi-normed
algebras are presented in this book. A brief introduction for functional
equations and their stability is provided with historical remarks. Since
the homomorphisms and derivations in Banach algebras are additive and
R-linear or C-linear, the stability problems for additive functional
equations and additive mappings are studied in detail. The latest
results are discussed and examined in stability theory for new
functional equations and functional inequalities in Banach algebras and
C*-algebras, non-Archimedean Banach algebras, non-Archimedean
C*-algebras, multi-Banach algebras and multi-C*-algebras.
Graduate students with an understanding of operator theory, functional
analysis, functional equations and analytic inequalities will find this
book useful for furthering their understanding and discovering the
latest results in mathematical analysis. Moreover, research
mathematicians, physicists and engineers will benefit from the variety
of old and new results, as well as theories and methods presented in
this book.
