We establish the existence and multiplicity of solutions for some boundary value problems on time scales with a \(\varphi\)-Laplacian operator. For this purpose, we employ the concept of lower and upper solutions and the Leray-Schauder degree. The re

Using Leray-Schauder degree theory and the method of upper and lower solutions we establish existence and multiplicity of solutions for problems of the form $$\displaylines{ (\phi(u'))' = f(t,u,u') \cr u(0)= u(T)=u'(0), }$$ where $\phi$ is an i

Using Leray-Schauder degree theory and the method of upper and lower solutions, we obtain a solution for nonlinear boundary-value problem $$\displaylines{ \big(\varphi(u' )\big)'= f(t,u,u') \cr l(u,u')=0, }$$ where l(u,u')=0 denotes the three-p

We provide new records of Neogale frenata and Potos flavus, two carnivores with elusive behaviors that are challenging to observe in their natural habitats. Through direct records compiled in diurnal and nocturnal monitoring over three years, we reco

We study the existence of solutions for nonlinear boundary value problems φu′′=ft,u,u′, lu,u′=0, where l(u,u′)=0 denotes the boundary conditions on a compact interval 0,T, φ is a homeomorphism such that φ(0)=0, and f:0,T×R×R→R is a c

This paper introduces fractional type evolutionary equations modeling the interaction between short waves and long waves. We consider a fractional Benney type system, which is given by a fractional Schr\"odinger equation coupled with a fractional por
