D-functor associated with cohomology

摘要

The aim of the present work is to follow the D-functors and modify it to be able to correct the errors in Cogosvili's paper on some properties of D-functions generated by cohomology. Moreover, we state and prove the sufficient conditions which guarantee the exactness of the D-functor. (author). 14 refs. (Atomindex citation 26:038526)
