Positive solutions for a class of telegraph system with multiparameters
Fanglei Wang and Yukun An
Hohai University, Nanjing University of Aeronautics and Astronautics
In this paper, we study the existence, non-existence, and multiplicity of positive solutions for a coupled telegraph system using the fixed-point theorem of cone expansion/compression type, the upper-lower solutions method, and fixed point index theory.
Keywords: telegraph system, doubly periodic solution, upper and lower solutions, fixed point theorem, cone
