In this paper, some new results on the existence and uniqueness of anti-periodic solution for a first-order impulsive functional differential equation with delay are obtained. The main tool to be employed here is the ...

In this work, we establish the existence and uniqueness of antiperiodic solution for a class of nth-order functional differential equations with infinite delay. The main tool in our study is the coincidence degree theory. ...

In this paper we study a new class of functions, which we call (omega, c)-periodic functions. This collection includes periodic, anti-periodic, Bloch and unbounded functions. We prove that the set conformed by these functions ...

In this paper we study a new class of functions, which we call (ω, c) -pseudo periodic functions. This collection includes pseudo periodic, pseudo anti-periodic, pseudo Bloch-periodic, and unbounded functions. We prove ...

In this paper, we study a new class of functions, which we call (omega, c)-asymptotically periodic functions. This collection includes asymptotically periodic, asymptotically antiperiodic, asymptotically Bloch-periodic, ...

The Schrödinger equation for periodic potentials on a ring is approached. For the free rotor, eigenfunctions of the angular momentum operator, as well as eigenfunctions of the parity operator are considered. It is demonstrated ...
