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 ...
The infinity Laplacian, a highly degenerate elliptic operator formally defined by Δ∞u = uₓᵢ uₓⱼ uₓᵢₓⱼ, has emerged as a central object in the study of L∞ variational problems and optimal Lipschitz ...
