Existence results and Ulam-Hyers stability for a sequential deformable fractional initial value problem

Leila Slimane, Souad Ayadi, Ozgur Ege, Ahmad Aloqaily et al. • Journal of Inequalities and Applications (2026)

Abstract In this study, we establish existence and Ulam-Hyers results for nonlinear sequential fractional differential equations involving the deformable derivative. We employ the Banach contraction principle and Krasnoselskii’s theorem to ...

Different Behavior of 2-Substituted 3-Nitro-2<i>H</i>-chromenes in the Reaction with Stabilized Azomethine Ylides Generated from α-Iminoesters

Ivan A. Kochnev, Alexey Y. Barkov, Nikita S. Simonov, Maria V. Ulitko et al. • Molecules (2022)

The AgOAc-catalysed reaction of 3-nitro-2-phenyl-2H-chromenes with stabilized azomethine ylides generated from the imines based on methyl glycinate and arylaldehydes leads to a mixture of endo and endo’ isomers of the corresponding chromeno...
