This article concerns the diffusion system ∂tu−∆xu + V (x)u = g(t, x, v), −∂tv −∆xv + V (x)v = f(t, x, u), where z = (u, v) : R × RN → R2, V (x) ∈ C(RN , R) is a general periodic function, g, f are periodic in t, x and asymptotically linear in u, v at infinity. We find a minimizing Cerami sequence of the energy functional outside the Nehari-Pankov manifold N and therefore obtain ground state so...
mation having made many contributions to interleukin-1 (IL-1) and TNF. For example, Ghezzi was the first to report that hypoxia induced IL-1β and TNFα. In addition to their own chapters, the invited contributions are easy to read and each addresses a different aspect of this growing field of investigation. Driving the field are the clinical trials of EPO in patients with cerebral vascular accid...
Ghezzi, P; Bernaudin, M; Bianchi, R; Blomgren, K; Brines, M; Campana, W; Cavaletti, G; Cerami, A; Chopp, M; Coleman, T; Digicaylioglu, M; Ehrenreich, H; Erbayraktar, S; Erbayraktar, Z; Gassmann, M; Genc, S; Gokmen, N; Grasso, G; Juul, S; Lipton, S A; Hand, C C; Latini, R; Lauria, G; Leist, M; Newton, S S; Petit, E; Probert, L; Sfacteria, A; Siren, A L; Talan, M; Thiemermann, C; Westenbrink, D; ...
<p style='text-indent:20px;'>In this paper, we consider the existence and asymptotic behavior of ground state solutions for a class Hamiltonian elliptic system with Hardy potential. The resulting problem engages three major difficulties: one is that associated functional strongly indefinite, second difficulty must overcome lies in verifying link geometry showing boundedness Cerami sequenc...
This paper is concerned with the following Schrödinger equation: { − u+ V (x)u = f(x, u), for x ∈ R , u(x) → 0, as |x| → ∞, where the potential V and f are periodic with respect to x and 0 is a boundary point of the spectrum σ(− + V ). By a new technique for showing the boundedness of Cerami sequences, we are able to obtain the existence of nontrivial solutions with mild assumptions on f .
We review typical compactness conditions used in variational techniques and some of their properties, the relationships between them. In particular, we provide new insights into results related to Palais-Smale Cerami conditions, comparison. See also https://ejde.math.txstate.edu/special/02/c3/abstr.html
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
In this paper the existence of two positive solutions for a Dirichlet problem having a critical growth, and depending on a real parameter, is established. The approach is based on methods which are totally variational, unlike the fundamental result of Ambrosetti, Brezis and Cerami where a clever combination of topological and variational methods is used in order to obtain the same conclusion. I...
