Membrane algorithms(MAs), which inherit from P systems, constitute a new parallel and distribute framework for approximate computation. In the paper, a membrane
Dehghan and Hajarian, [4], investigated the matrix equations ATXB +BTXTA =C and ATXB + BTXA = C providing inequalities for the determinant of the solutions of t
In this article we consider via critical point theory the existence of homoclinic orbits of the first-order differential difference equation˙z(t) +B(t)z(t) +f(
