The construction of ω-ultradistributions is an important problem in the research of linear partial differential operators.Some topological isomorphism relations between ω-ultradistributions and real-analytic functions can be set up by Fourier-Laplace transform
so that the constructions and properties of ω-ultradistributions can be studied by real-analytic functions.The constructions of two weighted real-analytic functions A(ω)(CN
Ω)andA(ω)(CN
Ω)are considered by using the properties of weight functions
