Asymptotic Convergence of the Solutions of a Dynamic Equation on Discrete Time Scales
The paper investigates a dynamic equation Δy(tn)=β(tn)[y(tn−j)−y(tn−k)] for n→∞, where k and j are integers such that k>j≥0, on an arbitrary discrete time scale T:={tn} with tn∈ℝ, n∈ℤn0−k∞={n0−k,n0−k+1,…}, n0∈ℕ ...

Existence of Solutions for Degenerate Elliptic Problems in Weighted Sobolev Space
This paper is devoted to the study of the existence of solutions to a general elliptic problem Au+g(x,u,∇u)=f-divF, with f∈L1(Ω) and F∈∏i=1NLp'(Ω,ωi*), where A is a Leray-Lions operator from a weighted Sobolev space into its dual and g(x,s,ξ) is a ...

Solutions of the Difference Equation 𝑥𝑛+1=𝑥𝑛𝑥𝑛−1−1
Our goal in this paper is to investigate the long-term behavior of solutions of the following difference equation: 𝑥𝑛+1=𝑥𝑛𝑥𝑛−1−1, 𝑛=0,1,2,…, where the initial conditions 𝑥−1 and 𝑥0 are real numbers. We examine the boundedness of solutions, periodicity of

Generic existence of solutions of nonconvex optimal control problems
The Tonelli existence theorem in the calculus of variations and its subsequent modifications were established for integrands f which satisfy convexity and growth conditions.
