In this paper we study the existence, multiplicity, and regularity of positive weak solutions for following Kirchhoff–Choquard problem: M ∬ ℝ 2 N | u ( x ) − y + s d Δ = λ γ ∫ Ω μ , ∗ in 0 \ where is open bounded domain with C2 boundary, > 2s ∈ (0, 1). models Kirchhoff-type coefficient particular, degenerate case Kirchhoff zero at zero. (− Δ)s fractional Laplace operator, a real parameter, 1) c...
[1] The conventional view of microwave backscatter from the ocean is based on composite surface and quasi-specular theories. In this view, backscatter at intermediate incidence angles is due to Bragg scattering from freely propagating short surface waves that are advected and modulated by longer waves. At small incidence angles the scattering process becomes quasi-specular, coming from small fa...
Abstract. This work presents a numerical framework for long dynamic simulations of structures made multiple thin shells undergoing large deformations. The C1-continuity requirement the Kirchhoff-Love theory is met in interior patches by cubic NURBS approximation functions with membrane locking avoided patch-wise reduced integration. A simple penalty approach coupling adjacent patches, applicabl...
Several topological indices are known to have widespread implications in a variety of research areas. Over the years, Kirchhoff index has turned out be an extremely significant and efficient index. In this paper, we propose exact formulas for expected values random polyomino chain construct multiplicative degree-Kirchhoff additive We also carefully examine highest degree through
In this article, by using critical point theory, we show the existence of infinitely many weak solutions for a fourth-order Kirchhoff type elliptic problems with Hardy potential.
in this paper, we prove a multiplicity result for some biharmonic elliptic equation of kirchhoff type and involving nonlinearities with critical exponential growth at infinity. using some variational arguments and exploiting the symmetries of the problem, we establish a multiplicity result giving two nontrivial solutions.
We give several examples of modeling in nonlinear elasticity where a quasiconvexification procedure is needed. We first recall that the three-dimensional Saint Venant-Kirchhoff energy fails to be quasiconvex and that its quasiconvex envelope can be obtained by means of careful computations. Second, we turn to the mathematical derivation of slender structure models: an asymptotic procedure using...
