Qual. Electronic Journal of Qualitative Theory of Differential Equations 2020, No. In this respect, our work can be considered as an extension of Yakubov's results to the case of boundary conditions containing a linear operator. The obtained abstract result is applied to a non regular boundary value problem for a second order partial differential equation of an elliptic type in a cylindrical domain. This paper is concerned with positive almost periodic type solutions to a class of nonlinear difference equation with delay. 60, pp. Honouring his memory, we recall the main events of his life when he was a student, then from the years in Saint Petersburg until 1885, from the Kharkov period, finally from his second period in Saint Petersburg from 1902.
