Opis:
We consider a nonlinear Neumann elliptic equation driven by the $p$-Laplacian and a Carathéodory perturbation. The energy functional of the problem need not be coercive. Using variational methods we prove an existence theorem and a multiplicity theorem, producing two nontrivial smooth solutions. Our formulation incorporates strongly resonant equations..

second deformation theorem
Opis:
We consider a nonlinear Neumann elliptic equation driven by a p-Laplacian-type operator which is not homogeneous in general. For such an equation the energy functional does not need to be coercive, and we use suitable variational methods to show that the problem has at least two distinct, nontrivial smooth solutions. Our formulation incorporates strongly resonant equations.

Opis:
Our aim was to perform a systematic open-access review of various complications reported for surgically assisted rapid maxillary expansion (SARME) procedures. There were 37 articles found in Pubmed using the search equation. Twelve articles were initially excluded according to the exclusion criteria. The 25 remaining articles were read in full for their descriptions of complications related to the SARME procedure in mature patients. The main reversible complications of SARME were infection, postoperative pain, and bleeding. There were also complications related to distractors, to secondary surgeries, and pterygomaxillary junction. The main non-reversible complications of SARME were associated with teeth, periodontal bone loss, and skull base fractures. Large field-of-view cone beam computed tomography (maxilla and skull base) should be implemented as initial planning tool to prevent many potential complications. The current trend for “minimally invasive” surgery in SARME might be, from an ethical point of view, transformed onto “minimally complicated” surgery as complication is still more harmful for any given patient than any potential perioperative surgical invasiveness.

Opis:
This paper contains a mountain pass theorem for continuous mappings, defined on a complete metric space and taking values in a real Banach space, ordered by a closed convex cone. We use the concept of critical point introduced by Degiovanni, Lucchetti and Ribarska, and we furnish a variant of their result, allowing for a localization both of the critical point and of the critical value.

Opis:
In this paper, we prove the existence of infinitely many weak bounded solutions of the nonlinear elliptic problem [formula], where [formula] is an open bounded domain, N ≥ 3, and [formula] are given functions, with[formula], such that A(x, •, •) is even and g(x, •) is odd. To this aim, we use variational arguments and the Rabinowitz's perturbation method which is adapted to our setting and exploits a weak version of the Cerami-Palais-Smale condition. Furthermore, if [formula] grows fast enough with respect to t, then the nonlinear term related to g(x,t) may have also a supercritical growth.

Opis:
In this paper we study a quasilinear resonant problem with discontinuous right hand side. To develop an existence theory we pass to a multivalued version of the problem, by filling in the gaps at the discontinuity points. We prove the existence of a nontrivial solution using a variational approach based on the critical point theory of nonsmooth locally Lipschitz functionals.
