On the Cauchy problem for linear hyperbolic functional-differential equations

Alexander Lomtatidze, Jiří Šremr (2012)

We study the question of the existence, uniqueness, and continuous dependence on parameters of the Carathéodory solutions to the Cauchy problem for linear partial functional-differential equations of hyperbolic type. A theorem on the Fredholm alternative is also proved. The results obtained are new even in the case of equations without argument deviations, because we do not suppose absolute continuity of the function the Cauchy problem is prescribed on, which is rather usual assumption...

In this paper, we are concerned with the existence of solutions of the following multi-point boundary value problem consisting of the higher-order differential equation x ( n ) ( t ) = f ( t , x ( t ) , x ' ( t ) , ⋯ , x ( n - 1 ) ( t ) ) + e ( t ) , 0 < t < 1 , ( * ) and the following multi-point boundary value conditions 1 * - 1 x ( i ) ( 0 ) = 0 f o r i = 0 , 1 , ⋯ , n - 3 , x ( n - 1 ) ( 0 ) = α x ( n - 1 ) ( ξ ) , x ( n - 2 ) ( 1 ) = ∑ i = 1 m β i x ( n - 2 ) ( η i ) . * * Sufficient conditions for the existence of at least one solution of the BVP ( * ) and ( * * ) at resonance are established. The results obtained generalize and complement those in [13, 14]. This paper is directly motivated by Liu and Yu [J. Pure Appl. Math. 33 (4)(2002),...
