This paper shows the existence and multiplicity of nontrivial solutions of the p-Laplacian problem -Δpu=1/σ(∂F(x,u)/∂u)+λa(x)|u|q-2u for x∈Ω with zero Dirichlet boundary conditions, where Ω is a bounded open set in ℝn, 1<q<p<σ<p*(p*=np/(n-p) if p<n, p*=∞ if p≥n), λ∈ℝ∖{0}, a is a smooth function which may change sign in Ω̅,, and F∈C1(Ω̅ × ℝ,ℝ). The method is based on Nehari results on three submanifolds of the space W01,p(Ω).

AbstractIn this paper we are interested to ensure the existence of multiple nontrivial solutions for some classes of problems under Dirichlet boundary conditions with impulsive effects. More precisely, by using a suitable analytical setting, the existence of at least three solutions is proved exploiting a recent three-critical points result for smooth functionals defined in a reflexive Banach space. Our approach generalizes some well-known results in the classical framework.

AbstractWe study existence and multiplicity results for solutions of elliptic problems of the type -Δu = g(x; u) in a bounded domain Ω with Dirichlet boundary conditions. The function g(x; s) is asymptotically linear as |s| → +∞. Also resonant situations are allowed. We also prove some perturbation results for Dirichlet problems of the type -Δu = g

Abstract We analyze $\begin{array}{} \frac{\pi}{4} \end{array} $-tangentiality of solutions for several types of scalar equations and systems of one-dimensional Minkowski-curvature problems with two points Dirichlet boundary conditions, which is dependent on singularity of weight functions and the growth of nonlinear terms. One of the goals is to show non $\begin{array}{} \frac{\pi}{4} \end{array} $-tangentiality (∥u′∥∞ < 1) of solutions for some of the above problems. We consider a larger class of weight functions and find out suitable nonlinear terms associated with it to keep non $\begin{array}{} \frac{\pi}{4} \end{array} $-tangentiality of solutions. Finally, we obtain Lyapunov-type inequalities for some nonlinear problems as by-products which also extend the results in some previous studies.

Abstract We find the most general solution to Chern-Simons AdS3 gravity in Fefferman-Graham gauge. The connections are equivalent to geometries that have a non-trivial curved boundary, characterized by a 2-dimensional vielbein and a spin connection. We define a variational principle for Dirichlet boundary conditions and find the boundary stress tensor in the Chern-Simons formalism. Using this variational principle as the departure point, we show how to treat other choices of boundary conditions in this formalism, such as, including the mixed boundary conditions corresponding to a $$ T\overline{T} $$ T T ¯ -deformation.

Abstract The gravitational charge algebra of generic asymptotically locally (A)dS spacetimes is derived in n dimensions. The analysis is performed in the Starobinsky/Fefferman-Graham gauge, without assuming any further boundary condition than the minimal falloffs for conformal compactification. In particular, the boundary structure is allowed to fluctuate and plays the role of source yielding some symplectic flux at the boundary. Using the holographic renormalization procedure, the divergences are removed from the symplectic structure, which leads to finite expressions. The charges associated with boundary diffeomorphisms are generically non-vanishing, non-integrable and not conserved, while those associated with boundary Weyl rescalings are non-vanishing only in odd dimensions due to the presence of Weyl anomalies in the dual theory. The charge algebra exhibits a field-dependent 2-cocycle in odd dimensions. When the general framework is restricted to three-dimensional asymptotically AdS spacetimes with Dirichlet boundary conditions, the 2-cocycle reduces to the Brown-Henneaux central extension. The analysis is also specified to leaky boundary conditions in asymptotically locally (A)dS spacetimes that lead to the Λ-BMS asymptotic symmetry group. In the flat limit, the latter contracts into the BMS group in n dimensions.
