Abstract

In the present paper, we study the direct power of hyperalgebras obtained as the subhyperalgebra of their direct product carried by good homomorphisms. We give sufficient conditions for the validity of the second exponential law and a weak form of the first exponential law. Moreover, we restrict the concepts of the direct powers from  hyperalgebras to algebras and give sufficient conditions for the validity of the first and the second exponential laws of algebras.
