The main aim of this paper is to develop some basic theories of neutral stochastic functional differential equations (NSFDEs). Firstly, we establish a local existenceuniqueness theorem under the local ...
The subject of this paper revolves around fractional differential equations incorporating a 𝜓-Caputo fractional derivative, focusing on the Ulam–Hyers stability , the existence and uniqueness of ...
Existence theorems constitute a fundamental pillar in the study of game theory and exchange economies. These theorems rigorously establish the conditions under which equilibria or stable outcomes ...
