This article examines a new family of (p, q)‐Laplacian type nonlinear fractional impulsive
differential coupled equations involving both the ψ ψ‐Caputo fractional derivative and ψ ψ …

In this article, by combining a recent critical point theorem and several theories of the ψ-
Caputo fractional operator, the multiplicity results of at least three distinct weak solutions are …

This paper considers a nonlinear impulsive fractional boundary value problem, which
involves a ψ-Caputo-type fractional derivative and integral. Combining critical point theory …

In the present paper we prove some results related to the minimal displacement of the DND-
Lipschitzian mappings. Such class of mappings are defined from the so called degree of …

This article is a subject about the existence results for a class of tempered ψ-Caputo
fractional differential equations. These problems encompassed nonlinear implicit neutral …

In this paper, under suitable conditions and by using the so-called degree of
nondensifiability (DND), we provide sufficient conditions for the existence of a common fixed …

In this paper, based on the so-called degree of nondensifiability (DND), we introduce the
concept of DND-convex-power condensing mapping which generalizes that of the DND …
