摘要：
The article compares the finitistic dimensions of two algebras involved in an idealized extension of Artin algebras under certain conditions. Precisely, we prove that, for the extension of Artin algebras B subset of A with the same identity, under the assumption that the Jacobson radical rad(B) of B is an ideal of A and that the quotient algebra A/rad(B) has Loewy length 2, if the global dimension of A is at most 4, then the finitistic dimension of B is finite.
