Efficiency in vector ratio variational control problems involving geodesic quasiinvex multiple integral functionals [PDF]

Archives of Control Sciences, 2021
In this paper, we introduce necessary and sufficient efficiency conditions associated with a class of multiobjective fractional variational control problems governed by geodesic quasiinvex multiple integral functionals and mixed constraints containing m ...

Classification of solutions for mixed order conformally system with Hartree-type nonlinearity in

Bulletin of Mathematical Sciences, 2023
In this paper, we consider the following mixed order conformally invariant system with Hartree-type nonlinearity : (−Δ)su(x) = 1 |x|σ ∗ v2n−σ n−2 vn+2s−σ n−2(x),in ℝn,(−Δ)v(x) = u n+2 n−2s(x), in ℝn,u ≥ 0,v ≥ 0, in ℝn,(0.1) where [Formula: see text ...

An Explicit Fourth-Order Compact Numerical Scheme for Heat Transfer of Boundary Layer Flow

Energies, 2021
The main contribution of this article is to propose a compact explicit scheme for solving time-dependent partial differential equations (PDEs). The proposed explicit scheme has an advantage over the corresponding implicit compact scheme to find solutions
