In this talk, we explain methods to compute them when the manifold is BV exact. This method can be applied to many examples, since any rationally formal space (or more generally a space admitting positive weights) is BV exact. We also give non-examples of BV exact spaces, which are found by a computer-assisted method. This is a joint work with Katsuhiko Kuribayashi, Takahito Naito, and Toshihiro Yamaguchi. </p><p class="" style="font-family: -webkit-standard;">窶披披披披披披披披披披披披披披披披披披披披披披� </p><p class="" style="font-family: -webkit-standard;">蟇ｾ髱｢縺ｧ縺ｮ繧ｻ繝溘リ繝ｼ縺ｧ縺吶� 閨ｴ隰幄��謇区欠縺ｮ豸域ｯ偵√�繧ｹ繧ｯ逹逕ｨ縲√た繝ｼ繧ｷ繝｣繝ｫ繝�ぅ繧ｹ繧ｿ繝ｳ繧ｹ遲画─譟鍋裸縺ｸ縺ｮ蟇ｾ遲悶↓縺泌鵠蜉帙＞縺溘□縺上ｈ縺�♀鬘倥＞縺励∪縺吶ゅ＃蜊泌鴨縺�◆縺�縺代↑縺��ｴ蜷医�縺秘螳､繧偵♀鬘倥＞縺吶ｋ蝣ｴ蜷医′縺ゅｊ縺ｾ縺吶ゅ∪縺滓─譟鍋裸縺ｸ縺ｮ蟇ｾ遲悶�縺溘ａ蜈･螳､莠ｺ謨ｰ繧貞宛髯舌☆繧句�ｴ蜷医′縺ゅｊ縺ｾ縺吶ら音縺ｫ隰帶ｼ秘幕蟋句ｾ後�蜈･螳､縺後〒縺阪↑縺上↑繧句�ｴ蜷医′縺ゅｊ縺ｾ縺吶ゅそ繝溘リ繝ｼ螳､縺ｫ譚･繧峨ｌ縺ｪ縺��隰帛ｸ梧悍閠��縺溘ａ縺ｫ繧ｪ繝ｳ繝ｩ繧､繝ｳ縺ｧ縺ｮ繧ｻ繝溘リ繝ｼ譏�蜒上�繝ｪ繧｢繝ｫ繧ｿ繧､繝�驟堺ｿ｡繧剃ｼ∫判縺励※縺翫ｊ縺ｾ縺吶ょｸ梧悍閠��莉･荳九�繝輔か繝ｼ繝�縺ｫ逋ｻ骭ｲ縺企｡倥＞縺励∪縺吶� �医☆縺ｧ縺ｫ蜑榊ｹｴ蠎ｦ荳ｭ縺ｫ逋ｻ骭ｲ縺�◆縺�縺�◆蝣ｴ蜷医�ZoomId繧貞ｼ輔″邯壹″縺泌茜逕ｨ縺�◆縺�縺代∪縺�.蜀榊ｺｦ逋ｻ骭ｲ縺�◆縺�縺丞ｿ�ｦ√�縺ゅｊ縺ｾ縺帙ｓ) <a href="https://docs.google.com/forms/d/1QZr7GchFF8xlElZd-0k2XTBKm5V6_tStFcjku-p30Pg/edit" class="">https://docs.google.com/forms/d/1QZr7GchFF8xlElZd-0k2XTBKm5V6_tStFcjku-p30Pg/edit</a>縲</p></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;"><br class=""></span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;">2022/5/23(Mon) 蟷ｾ菴輔そ繝溘リ繝ｼ</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">13:00--14:30 逅�ｭｦ驛ｨ E404/406/408 螟ｧ繧ｻ繝溘リ繝ｼ螳､</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">逕倅ｸｭ荳霈�(逅���)</span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;"><br class=""></span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;">2022/5/30(Mon) </span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">13:00--14:30 </span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">荵�悽譎ｺ荵�(譚ｱ莠ｬ驛ｽ遶句､ｧ蟄ｦ)</span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;"><br class=""></span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;">2022/6/20(Mon) 蟷ｾ菴輔そ繝溘リ繝ｼ</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">13:00--14:30 逅�ｭｦ驛ｨ E404/406/408 螟ｧ繧ｻ繝溘リ繝ｼ螳､</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">莠暮未陬暮摶(諷ｶ諛臥ｾｩ蝪ｾ螟ｧ蟄ｦ)</span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;"><br class=""></span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;">2022/7/25(Mon) 蟷ｾ菴輔そ繝溘リ繝ｼ</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">13:00--14:30 逅�ｭｦ驛ｨ E404/406/408 螟ｧ繧ｻ繝溘リ繝ｼ螳､</span><br class="" style="font-family: -webkit-standard;"><span class="" style="font-family: -webkit-standard; font-size: medium;">螻ｱ蟾晏､ｧ莠ｮ(譚ｱ莠ｬ逅�ｧ大､ｧ)</span></div><div class=""><span class="" style="font-family: -webkit-standard; font-size: medium;"><br class=""></span></div><div class=""><font face="-webkit-standard" size="3" class="">莉･荳翫�</font></div><div class=""><div class="">逧�ｧ倥�縺泌盾蜉�繧偵％縺薙ｍ繧医ｊ縺雁ｾ�■縺励※縺翫ｊ縺ｾ縺吶�</div><div class="">繧医ｍ縺励￥縺企｡倥＞縺励∪縺吶�</div><div class=""><br class=""></div><div class="">邉溯ｰｷ</div></div></div></body></html>
