Multiple solutions for Schrodinger-Maxwell systems with unbounded and decaying radial potentials
Electronic Journal of Differential Equations, 2014 This article concerns the nonlinear Schrodinger-Maxwell system $$\displaylines{ -\Delta u +V(|x|)u +Q(|x|)\phi u=Q(|x|) f(u),\quad \hbox{in } \mathbb{R}^3\cr -\Delta \phi =Q(|x|) u^{2}, \quad \hbox{in } \mathbb{R}^3 }$$ where V and Q are unbounded ...

Ground-state solutions of a Hartree–Fock type system involving critical Sobolev exponent
Electronic Journal of Qualitative Theory of Differential EquationsIn this paper, ground-state solutions to a Hartree–Fock type system with a critical growth are studied. Firstly, instead of establishing the local Palais–Smale (P.-S.) condition and estimating the mountain-pass critical level, a perturbation method is ...

Mountain Pass on a Closed Convex Set
Journal of Mathematical Analysis and Applications, 1997 The author proves a version of the mountain pass theorem for a functional defined on a closed convex set of a Banach space. Such a functional does not necessarily satisfy the Palais-Smale condition. This abstract result is applied to the study of the semilinear Dirichlet problem \[ \begin{cases} -\Delta u+u^2 =f(x) \quad & \text{in } \Omega,\\ u=0 ...

Whole‐bone shape of hominoid manual proximal phalanges
The Anatomical Record, EarlyView.Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Multiple solutions for semilinear elliptic boundary value problems at resonance
Electronic Journal of Differential Equations, 1995 successful in proving the existence of weak solutions for semilinear elliptic boundary value problems at resonance. One technique involves a variational approach where solutions are characterized as saddle points for a related functional.

A Mountain Pass Theorem for a Suitable Class of Functions
Rocky Mountain Journal of Mathematics, 2009 In this article, a mountain pass theorem is obtained for a functional of the form \(J=\Phi-\Psi\) defined on a reflexive real Banach space, where \(\Phi\) and \(\Psi\) are continuously Gâteau differentiable functions, \(\Phi\) is convex, and \(J_M = \Phi-\Psi_M\) satisfies the Palais--Smale condition (PS)\(_c\) with \(\Psi_M\) the cut-off function at a

Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece
Archaeological Prospection, EarlyView.ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.
