We first establish the existence of solitary wave solutions for the equation without delay. And then we prove the existence of solitary wave solutions for the equation with a special local delay convolution kernel and a special nonlocal delay convolution kernel by using the method of dynamical system, especially the geometric singular perturbation theory and invariant manifold theory. According to the relationship between solitary wave and homoclinic orbit, the Camassa-Holm equation is transformed into the ordinary differential equations with fast variables by using the variable substitution. It is proved that the equation with disturbance also possesses homoclinic orbit, and there exists solitary wave solution of the delayed Camassa-Holm equation.</td> </tr> </table> <div id="vsb_content"><div class="v_news_content"> <p><span style="font-family: 宋体,SimSunFONT-FAMILY: 隶书; font-size: 16px">杜增吉,江苏师范大学教授。</span></p> </div></div><div id="div_vote_id"></div> </div> <div class="number"> <p>上一篇:<a href="/html/info104520399.html">Coercivity of fractional derivatives and application in an inverse source problem for fractional diffusion equation(I)</a></p> <p>下一篇:<a href="/html/info104520392.html">One-phase bifurcation for the p-Laplacian</a></p> </div> </form></div> </div> </div> </div> <div class="clear"></div> <div class="footer"> <div class="foot"> <div class="foot_l"> <div class="link"> <div><select onchange="_openSelectLink(this, 'value', 'addclicks')"> <option>校外链接</option> <option value="http://159.226.47.206/cms/index.htm" title="" addclicks="_addDynClicks("wburl", 1200121671, 47060)">中国数学会</option> <option value="http://www.nsfc.gov.cn/nsfc/cen/00/kxb/sw/index.htm" title="" addclicks="_addDynClicks("wburl", 1200121671, 47061)">国家基金委数理学部</option> <option value="http://www.math.hkbu.edu.hk/UniformDesign/society/main.htm" title="" addclicks="_addDynClicks("wburl", 1200121671, 47062)">中国数学均匀设计分会</option> <option value="http://www.nim.nankai.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47063)">陈省身数学研究所</option> <option value="http://www.math.pku.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47064)">北大数学</option> <option value="http://math.fudan.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47065)">复旦数学</option> </select></div><div><select onchange="_openSelectLink(this, 'value', 'addclicks')"> <option>校内链接</option> <option value="http://www.ccnu.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47066)">华中师范大学</option> <option value="http://www.hzu.net.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47067)">华大桂声</option> <option value="http://jwc.ccnu.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47068)">华师教务</option> <option value="http://career.ccnu.edu.cn/ccnujy/jiuyeIndex.do?method=indexPage" title="" addclicks="_addDynClicks("wburl", 1200121671, 47069)">华中师大就业网</option> <option value="http://tw.ccnu.edu.cn/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47070)">桂苑青年</option> <option value="http://www.shuxuetongxun.com/" title="" addclicks="_addDynClicks("wburl", 1200121671, 47071)">数学通讯</option> <option value="../../sxwlhbzdsys.htm" title="" addclicks="_addDynClicks("wburl", 1200121671, 47072)">数学物理湖北省重点实验室</option> <option value="http://blog.sina.com.cn/shifansheng2007" title="" addclicks="_addDynClicks("wburl", 1200121671, 47073)">王潇和她志同道合的人</option> </select></div> </div> <div class="copy"> <p><span style="color:#000000"><a href="/html/info1045....index.html">版权所有 ? 2010 华中师范大学数学与统计学学院</a> </span></p></div> </div> <div class="foot_r"> <ul> <li><a href="#" target="_blank" onclick="_addDynClicks("wbimage", 1200121671, 44953)"><img src="/images/newdfiles21178mathsccnuimgfootr03.png"><p>官方微博</p></a><div class="weix"><img src="/images/newdfiles21178mathsccnuimgweibo.jpg"></div></li> <li><a href="#" target="_blank" onclick="_addDynClicks("wbimage", 1200121671, 44952)"><img src="/images/newdfiles21178mathsccnuimgfootr02.png"><p>官方微信</p></a><div class="weix"><img src="/images/newdfiles21178mathsccnuimgweixin.jpg"></div></li> <li><a href="/html/info1045....newzxtg.jspurltypetree.TreeTempUrl&wbtreeid1078.html" target="_blank" onclick="_addDynClicks("wbimage", 1200121671, 44951)"><img src="/images/newdfiles21178mathsccnuimgfootr01.png"><p>在线投稿</p></a></li> </ul></div> </div> </div> <script type="text/javascript" src="/tongji.js"></script></body> </html>
