HUSEYN AHMADOV, Humeyir  e  ZULFIQAR HUMBATALIEV, Rovshan. On the solvability of some boundary value problems for operator-differential problems in a finite interval. Universidad y Sociedad [online]. 2021, vol.13, n.6, pp. 265-274.  Epub 10-Dez-2021. ISSN 2218-3620.

In this paper, conditions are obtained for the coefficients of one class of operator-differential equations of the fourth order, which ensure the solvability of some boundary value problems correctly posed for these equations. Moreover, a connection is indicated between the solvability of boundary value problems and the exact value of the norm of operators of intermediate derivatives in some subspaces.
