Abstract:The nonlocal boundary value problem for hyperbolic-parabolic equationsfor differential equation in a Hilbert space H, with the self-adjoint positive definite operator A is considered. The stability estimates for the solution of this problem are established. In applications, the stability estimates for the solutions of the mixed type boundary value problems for hyperbolic-parabolic equations are obtained.
“…Using the last formula and the estimates (3), (4), (5) and (6), we can obtain Now, we will obtain the same estimates for the norm of u.t/, A 1=2 u.t/ and Au.t/. Using the identities (13) and (14) and the estimates (3), (4), (5), (6), we obtain…”

“…They also play a very important role for mathematical modelling in many branches of science, engineering and industry. Theory and numerical methods of solutions of the boundary value problems endowed with the local and nonlocal boundary conditions for partial differential equations have been investigated by many researchers ( [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and the references therein).…”

The first-order of accuracy difference scheme for approximately solving the multipoint nonlocal boundary value problemfor the differential equation in a Hilbert space H , with self-adjoint positive definite operator A is presented. The stability estimates for the solution of this difference scheme are established. In applications, the stability estimates for the solution of difference schemes of the mixed type boundary value problems for hyperbolic-parabolic equations are obtained.

The present survey contains the recent results on the local and nonlocal well-posed problems for second order differential and difference equations. Results on the stability of differential problems for second order equations and of difference schemes for approximate solution of the second order problems are presented.
