Abstract

. In this paper, we consider the following damped vibration system ¨ u ( t )+ q ( t ) ˙ u ( t ) − L ( t ) u ( t )+ ∇ W ( t , u ( t )) = 0 , ∀ t ∈ R , where q ∈ C ( R , R ) , L ∈ C ( R , R N 2 ) is a symmetric matrix valued function and W ( t , x ) ∈ C 1 ( R × R N , R ) . We prove the existence of inﬁnitely many fast homoclinic solutions for the system when Q ( t ) = (cid:82) t 0 q ( s ) ds → + ∞ as | t | → ∞ , L is neither coercive nor uniformly positive deﬁnite and W ( t , x ) is superquadratic at inﬁnity in the second variable but does not satisfy the well-known superquadratic growth conditions like the Ambrosetti-Rabinowitz or the Fei’s conditions.

一类超二次阻尼振动系统的无穷多快速同斜轨道

．在本文中,我们考虑下面的阻尼振动系统¨u (t) + q (t)˙u (t)−L (t) u (t) +∇W (t, u (t)) = 0,∀t∈R, q∈C (R, R), L∈C (R, R N 2)是一个对称矩阵值函数和W C (t) x)∈1 (R×R N, R)。我们证明存在无穷多快类解决方案系统时问(t) = (cid: 82) t 0 Q (s) ds→+∞| | t→∞,L是强制性和均匀正定和W (t, x)超是在第二个变量但无穷满足超有名的生长条件不像范Ambrosetti-Rabinowitz或的条件。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
