Journal of Applied Mathematics, 2013 This paper is devoted to multiple solutions of generalized asymptotical linear Hamiltonian systems satisfying Bolza boundary conditions. We classify the linear Hamiltonian systems by the index theory and obtain the existence and multiplicity of solutions

Canadian Journal of Economics/Revue canadienne d'économique, Volume 58, Issue 4, Page 1638-1663, November 2025.Abstract Do discriminatory attitudes held in the public influence public institutions? We study this question within the context of the criminal justice system of historical British Columbia (BC). During the late 1870s and early 1880s, an influx of Chinese immigrant workers employed in the building of the Canadian Pacific Railway (CPR) was the catalyst

Homoclinic orbits for a class of symmetric Hamiltonian systems
Electronic Journal of Differential Equations, 1994 of Hamiltonian systems that are symmetric with respect to independent variable (time). For the scalar case we prove existence and uniqueness of a positive homoclinic solution. For the system case we prove existence of symmetric homoclinic orbits.

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Brezis–Nirenberg type results for the anisotropic p$p$‐Laplacian
Journal of the London Mathematical Society, Volume 112, Issue 4, October 2025.Abstract In this paper, we consider a quasilinear elliptic and critical problem with Dirichlet boundary conditions in presence of the anisotropic p$p$‐Laplacian. The critical exponent is the usual p★$p^{\star }$ such that the embedding W01,p(Ω)⊂Lp★(Ω)$W^{1,p}_{0}(\Omega) \subset L^{p^{\star }}(\Omega)$ is not compact.

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.Abstract Converting forests and grasslands to farms can impact soil properties and increase acidity. This study examines the effects of various land use types (LUTs) (cultivated, grazing, and forest) on soil characteristics and surface acidity in the Hula and Gorche districts of southern Ethiopia, analyzing 72 soil samples from six villages.

On ground state for a class of nonlinear Schrödinger equation
Journal of Taibah University for Science, 2018 I study the existence of ground state for the following periodic Schrödinger equation under the circumstance that the nonlinear term satisfies odd conditions by using the Mountain Pass Lemma and variational method. $$-\Delta u+V(x)u-\Delta(1+u^2)^{{1}/{2}

Mathematische Nachrichten, Volume 298, Issue 8, Page 2570-2595, August 2025.Abstract We discuss the existence theory of a nonlinear problem of nonlocal type subject to Neumann boundary conditions. Differently from the existing literature, the elliptic operator under consideration is obtained as a superposition of operators of mixed order. The setting that we introduce is very general and comprises, for instance, the sum of two
