On a periodic boundary value problem for second-order linear functional differential equations
Unimprovable efficient sufficient conditions are established for the unique solvability of the periodic problem u″(t)=ℓ(u)(t)+q(t) for 0≤t≤É, u(i)(0)=u(i)(É)(i=0,1), where É>0, ℓ:C([0,É])→L([0,É]) is a linear bounded operator, and q∈L([0,É])....
