Solutions with a prescribed interval of positivity for differential systems with nonlocal conditions

July 2, 2020

AbstractBased on fixed point index, the paper develops a theory of existence, localization and multiplicity of solutions to first-order differential systems subject to linear nonlocal conditions. The main features concern…
