Fixed points and quadratic equations connected with homomorphisms and derivations on non-Archimedean algebras
We apply the fixed point method to prove the stability of the systems of functional equations on non-Archimedean Banach algebras. Moreover, we give some applications of our results in non-Archimedean Banach algebras over p-adic numbers. MSC:34K36, 46S40, 47S40, 39B82, 39B52, 26E50.
