Abstract


The paper continues the investigation of the spaces of complex-valued perfect splines Ωn(m). These spaces were introduced as generalization of the spaces Ωn, the topology of which has been studied by V.I. Ruban, V.A. Koshcheev, A.M. Pasko. In our previous papers the homology groups of the spaces Ωn(m) have been found and their simply connectedness was established. The topic of the paper is finding of the homology groups of the Cartesian product Ωn1(m1)×Ωn2(m2). In order to find the homology groups of this Cartesian product the Kunneth theorem has been used. Using the Kunneth theorem and the fact that Tor(A,B)=0 if at least one of the group A,B is free we presented the homology group of the Cartesian product Ωn1(m1)×Ωn2(m2) as the sum of the tensor products of the homology groups of this spaces. Calculating the tensor products we found the homology groups of Ωn1(m1)×Ωn2(m2).
