1. Normalized solutions for INLS equation with critical Hardy-Sobolev type nonlinearities

Subjects
Mathematics - Analysis of PDEs, 35B08, 35J75, 35J92, 35B33
Abstract

We are interested in finding prescribed $L^2$-norm solutions to inhomogeneous nonlinear Schr\"{o}dinger (INLS) equations. For $N\ge 3$ we treat the equation with combined Hardy-Sobolev power-type nonlinearities $$ -\Delta u+\lambda u=\mu|x|^{-b}|u|^{q-2}u+|x|^{-d}|u|^{2^*_{d}-2}u \;\;\mbox{in}\;\; \mathbb{R}^N,\, N\ge 3 $$ where $\lambda\in\mathbb{R}$, $\mu>0$, $0

2. On a supercritical Hardy-Sobolev type inequality with logarithmic term and related extremal problem

Author

Subjects
Mathematics - Analysis of PDEs, 46E35, 35J35, 35J61, 35B33
Abstract

Our main goal is to investigate supercritical Hardy-Sobolev type inequalities with a logarithmic term and their corresponding variational problem. We prove the existence of extremal functions for the associated variational problem, despite the loss of compactness. As an application, we show the existence of weak solution to a general class of related elliptic partial differential equations with a logarithmic term.

Abstract

Critical Sobolev-type inequality for a class of weighted Sobolev spaces on the entire space is established. We also investigate the existence of extremal function for the associated variational problem. As an application, we prove the existence of a weak solution for a general class of critical semilinear elliptic equations related to the polyharmonic operator.

6. Conformal solitons for the mean curvature flow in hyperbolic space

Author

Mari, Luciano, de Oliveira, Jose Danuso Rocha, Savas-Halilaj, Andreas, and de Sena, Renivaldo Sodre

Subjects
Mathematics - Differential Geometry, Mathematics - Analysis of PDEs
Abstract

In this paper we study conformal solitons for the mean curvature flow in hyperbolic space $\mathbb{H}^{n+1}$. Working in the upper half-space model, we focus on horo-expanders, which relate to the conformal field $-\partial_0$. We classify cylindrical and rotationally symmetric examples, finding appropriate analogues of grim-reaper cylinders, bowl and winglike solitons. Moreover, we address the Plateau and the Dirichlet problems at infinity. For the latter, we provide the sharp boundary convexity condition to guarantee its solvability, and address the case of noncompact boundaries contained between two parallel hyperplanes of $\partial_{\infty}\mathbb{H}^{n+1}$. We conclude by proving rigidity results for bowl and grim-reaper cylinders.

Subjects
Mathematics - Analysis of PDEs
Abstract

We establish a supercritical Trudinger-Moser type inequality for the $k$-Hessian operator on the space of the $k$-admissible radially symmetric functions $\Phi^{k}_{0,\mathrm{rad}}(B)$, where $B$ is the unit ball in $\mathbb{R}^{N}$. We also prove the existence of extremal functions for this new supercritical inequality.

11. A gradient type term for the $k$-Hessian equation

Author

Cardoso, Mykael de Araújo, Sousa, Jefferson de Brito, and de Oliveira, José Francisco

Subjects
Mathematics - Analysis of PDEs, 35J66, 35J60, 35J50, 35J96
Abstract

In this paper, we propose a gradient type term for the $k$-Hessian equation that extends for $k>1$ the classical quadratic gradient term associated with the Laplace equation. We prove that such as gradient term is invariant by the Kazdan-Kramer change of variables. As applications, we ensure the existence of solutions for a new class of $k$-Hessian equation in the sublinear and superlinear cases for Sobolev type growth. The threshold for existence is obtained in some particular cases. In addition, for the Trudinger-Moser type growth regime, we also prove the existence of solutions under either subcritical or critical conditions.

22. On a sharp inequality of Adimurthi-Druet type and extremal functions

Subjects

Abstract

Our main purpose in this paper is to establish the existence and nonexistence of extremal functions for sharp inequality of Adimurthi-Druet type for fractional dimensions on the entire space. Precisely, we extend the sharp Trudinger-Moser type inequality in (Calc.Var.Partial Differential Equations, \textbf{52} (2015) 125-163) for the entire space. In addition, we perform the two-step strategy of Carleson-Chang together blow up analysis method to ensure the existence of maximizers for the associated extremal problems for both subcritical and critical regimes. We also present a nonexistence result under subcritical regime for some special cases.

32. Equivalence of critical and subcritical sharp Trudinger-Moser inequalities in fractional dimensions and extremal functions

Author

Subjects
Mathematics - Analysis of PDEs
Abstract

We establish critical and subcritical sharp Trudinger-Moser inequalities for fractional dimensions on the whole space. Moreover, we obtain asymptotic lower and upper bounds for the fractional subcritical Trudinger-Moser supremum from which we can prove the equivalence between critical and subcritical inequalities. Using this equivalence, we prove the existence of maximizers for both the subcritical and critical associated extremal problems. As a by-product of this development, we can explicitly calculate the value of the critical supremum in some special situations.

42. Estimate for concentration level of the Adams functional and extremals for Adams-type inequality

Author

de Oliveira, José Francisco Alves and Macedo, Abiel Costa

Subjects
Mathematics - Analysis of PDEs, 35J60, 35J30, 31B30, 35B33
Abstract

This paper is mainly concerned with the existence of extremals for the Adams inequality. We first establish an upper bound for the classical Adams functional along of all concentrated sequences in $W^{m,\frac{n}{m}}_{\mathcal{N}}(\Omega)$, in particular in $W^{m,\frac{n}{m}}_{0}(\Omega)$, where $\Omega$ is a smooth bounded domain in Euclidean $n$-space. Secondly, based on the Concentration-compactness alternative due to Do \'{O} and Macedo, we prove the existence of extremals for the Adams inequality under Navier boundary conditions for second order derivatives at least for higher dimensions when $\Omega$ is an Euclidean ball.
