Suppose that is a Banach space and is aninjective operator in (), the space of all bounded linearoperators on . In this note, a two-parameter -semigroup(regularized semigroup) of operators is introduced, and some of itsproperties are discussed. As an application we show that theexistence and uniqueness of solution of the 2-abstract Cauchyproblem (/())(1,2)=(1,2),=1,2, >0, (0,0)=, ∈((1)∩(2)) is closely related to the two-parameter -semigroups ofoperators
