The set of common fixed points of an n-parameter continuous semigroup of mappings

In this paper, using Kronecker's theorem, we discuss the set of common fixed points of an n-parameter continuous semigroup {T(p):p∈R+n} of mappings. We also discuss some convergence theorems to a common fixed point of an n-parameter nonexpansive semigroup {T(p):p∈R+n} without using the Bochner integral.
