Variational approach to a class of impulsive differential equations
In this article, the author discusses the existence of solutions for a class of impulsive differential equations by means of a variational approach different from earlier approaches.MSC:34B37, 45G10, 47H30, 47J30.

Existence and multiplicity results for fractional p(x)-Laplacian Dirichlet problem
In this paper, we study a class of fractional p(x)-Laplacian Dirichlet problems in a bounded domain with Lipschitz boundary. Using variational methods, we prove in different situations the existence and multiplicity of solutions.

Nonsmooth set variational inequality problems and optimality criteria for set optimization
In this work, set-valued optimization problems are considered according to an order relation, which is a partial order on the family such that contains nonempty bounded sets of the space. A generalized convexity is defined for set-valued mapping by using

On a version of Trudinger-Moser inequality with M\"obius shift invariance [PDF]
The paper raises a question about the optimal critical nonlinearity for the Sobolev space in two dimensions, connected to loss of compactness, and discusses the pertinent concentration compactness framework. We study properties of the improved version of

Fixed points of nonexpansive potential operators in Hilbert spaces
In this paper, we show the impact of certain general results by the author on the topic described in the title. Here is a sample:Let (X,〈⋅,⋅〉) be a real Hilbert space and let T:X→X be a nonexpansive potential operator.Then, the following alternative ...

From Nash to Cournot-Nash equilibria via the Monge-Kantorovich problem [PDF]
The notion of Nash equilibria plays a key role in the analysis of strategic interactions in the framework of $N$ player games. Analysis of Nash equilibria is however a complex issue when the number of players is large.

Simple study designs in ecology produce inaccurate estimates of biodiversity responses
We suggest that more investment in more robust designs is needed in ecology since inferences from simpler designs, even with large sample sizes may be misleading. Facilitating this requires longer‐term funding and stronger research–practice partnerships. We also propose ‘accuracy weights’ and demonstrate how they can weight studies in three recent meta‐

Existence of fast homoclinic orbits for a class of second-order non-autonomous problems
By applying the mountain pass theorem and the symmetric mountain pass theorem in critical point theory, the existence and multiplicity of fast homoclinic solutions are obtained for the following second-order non-autonomous problem: u¨(t)+q(t)u˙(t)−a(t)|u(

An optimal bound for nonlinear eigenvalues and torsional rigidity on domains with holes
In this paper we prove an optimal upper bound for the first eigenvalue of a Robin-Neumann boundary value problem for the p-Laplacian operator in domains with convex holes.
