Then for a certain parameter range it is now known that chaotic vibration occurs. However, if the right-end van der Pol boundary condition contains an extra linear displacement feedback term, then it induces a memory effect and considerable technical difficulty arises as to how to define and determine chaotic vibration of the system. In this paper, we take advantage of the extra margin property of the reflection map and utilize properties of homoclinic orbits coupled with a perturbation approach to show that for a small parameter range, chaotic vibrations occur in the sense of unbounded growth of snapshots of the gradient. The work also has significant implications to the occurrence of chaotic vibration for the wave equation on a 3D annular domain.<\/jats:p>","DOI":"10.1142\/s0218127402004838","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:05:54Z","timestamp":1027767954000},"page":"965-981","source":"Crossref","is-referenced-by-count":18,"title":["ANALYZING DISPLACEMENT TERM'S MEMORY EFFECT IN A VAN DER POL TYPE BOUNDARY CONDITION TO PROVE CHAOTIC VIBRATION OF THE WAVE EQUATION"],"prefix":"10.1142","volume":"12","author":[{"given":"GOONG","family":"CHEN","sequence":"first","affiliation":[{"name":"Department of Mathematics, Texas A&amp;M University, College Station, TX 77843, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SZE-BI","family":"HSU","sequence":"additional","affiliation":[{"name":"Department of Mathematics, National Tsing Hua University, Hsinchu 30043, Taiwan, R.O.C."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TINGWEN","family":"HUANG","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Texas A&amp;M University, College Station, TX 77843, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","unstructured":"G.\u00a0Chen and J.\u00a0Zhou, Vibration and Damping in Distributed Systems, Vol. I: Analysis, Estimation, Attenuation and Design (CRC Press, Boca Raton, FL, 1993)\u00a0p. 15."},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127496000898"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1090\/S0002-9947-98-02022-4"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127498000280"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127498000292"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1063\/1.532670"},{"key":"rf7","doi-asserted-by":"crossref","unstructured":"G.\u00a0Chen, Control of Nonlinear Distributed Parameter System, Lecture Notes in Pure and Applied Mathematics Series\u00a0218, eds.
