MacPherson introduced the notion of local Euler obstruction.A characteristic class for a local Euler obstruction was defined by using Nash blow-ups, and is called the Chern-Mather class or Chern-Schwartz-MacPherson class. The Gauss-Bonnet-Chern theorem is generalized to singular spaces by the top Chern-Schwartz-MacPherson classes. Inspired by gauge theory in higher dimension and string theory, the curve counting theory via stable coherent sheaves was constructed by Donaldson-Thomas on projective 3-folds, which is now called the Donaldson-Thomas theory. </td> </tr> <tr> <td class="title">Brief Introduction to Speaker</td> <td><div id="vsb_content"><div class="v_news_content"> 蒋云峰教授,美国堪萨斯大学? </div></div></td> </tr> </table> <ul style="margin-top:30px"> <li>上一条: <a href="/html/kxyj..info104519757.html">Survey on Ginzburg-Landau Models</a></li> <li>下一条: <a href="/html/kxyj..info104519753.html">Gluing method and blow-up solutions for the energy critical nonlinear heat equation</a></li> </ul> </div> </form> </div></div> <div class="clear"></div> </div> <div class="hezuo cleartf" style="clear: both"> <div class="linkWrap"> <div style="text-align: center;margin: 5px auto 0px"><script language="javascript" src="/images/systemresourcejsopenlink.js"></script> <a href="/html/kxyj..info1045....gywzwzjj.html" target="_blank" onfocus="undefined">网站简?/a> | <a href="/html/kxyj..info1045....zxtg_content.jspurltypetree.TreeTempUrl&wbtreeid1078.html" target="_blank" onfocus="undefined">在线投稿</a> | <a href="/html/kxyj..info1045....ldxx_content.jspurltypetree.TreeTempUrl&wbtreeid1081.html" target="_blank" onfocus="undefined">领导信箱</a> | <a href="/html/kxyj..info1045....gywzyqlj.html" target="_blank" onfocus="undefined">友情链接</a> <br> <FONT color="#000000"><A href="/html/kxyj..info1045....index.html">版权所?© 2010 华中师范大学数学与统计学学院</A> </FONT></div></div></div> <script type="text/javascript" src="/tongji.js"></script></body></html>
