Let be a compact Hausdorff space and let be a topological involution on . In 1988, Kulkarni and Arundhathi studied Choquet and Shilov boundaries for real uniform function algebras on . Then in 2000, Kulkarni and Limaye studied the concept of boundari

We investigate under what conditions n-Jordan homomorphisms between rings are n- homomorphism, or homomorphism; and under what conditions, n-Jordan homomorphisms are continuous.One of the main goals in this work is to show that every n-Jordan homomor

For $$n\ge 2$$ , an additive map f between two rings A and B is called an n-Jordan homomorphism, or an n-homomorphism if $$f(a^n)=f(a)^n$$ , for all $$a\in A$$ , or $$f(a_1a_2\cdots a_n)=f(a_1)f(a_2)\cdots f(a_n)$$ , for all $$a_1,a_2,\ldots ,a_n\in

A linear functional T on a Fr´echet algebra (A,(p n )) is calledalmost multiplicative with respect to the sequence (p n ), if there existse≥ 0 such that |Tab− TaTb| ≤ ep n (a)p n (b) for all n∈ N and for everya,b∈ A.We show that an almost

We extend the notion of homomorphisms and characters to $$n$$ -homomorphisms and $$n$$ -characters on algebras, and then show that some properties of characters are also valid for $$n$$ -characters on commutative $$lmc$$ topological algebras, and the

A map θ:A→B between algebras A and B is called n-multiplicative if θ(a1a2⋯an)=θ(a1) θ(a2)⋯θ(an) for all elements a1,a2,…,an∈A. If θ is also linear then it is called an n-homomorphism. This notion is an extension of a homomorphism. We

Let X be a compact, plane set and let K be a compact subset of X . We introduce new classes of Lipschitz algebras Lip( X , K , α ), lip( X , K , α ), consisting of those continuous functions f on X such that f|K ε Lip( K , α ), lip( K
