A Two-Point Boundary Value Problem with Reflection of the Argument

We consider the following two-point boundary value problems u″x+uπ−x+gx,uπ−x=hx in 0,π,u0=0=uπ, and u″x+uπ−x−gx,uπ−x=−hx in 0,π,u0=0=uπ, by setting h∈L10,π and g:0,π×R⟶R being a Caratheodory function. When a,b∈L10,π, ax≤3 for x∈0,π a.e. with strict inequality on a positive measurable subset of 0,π,...

description We consider the following two-point boundary value problems u″x+uπ−x+gx,uπ−x=hx in 0,π,u0=0=uπ, and u″x+uπ−x−gx,uπ−x=−hx in 0,π,u0=0=uπ, by setting h∈L10,π and g:0,π×R⟶R being a Caratheodory function. When a,b∈L10,π, ax≤3 for x∈0,π a.e. with strict inequality on a positive measurable subset of 0,π, and gx,u≤axu+bx for x∈0,π a.e. as well as sufficiently large u, several existence theorems will be obtained, with or without a sign condition.
