It is natural to ask whether one can establish analogies to Morse inequalities on CR manifolds by studying the asymptotic behaviour of the heat kernel. In this talk, I will show how to establish the heat kernel asymptotics for Kohn Laplacian (particularly in the Heisenberg case) with values in high tensor power of line bundle. As an application, it provides a heat kernel proof of Morse inequalities on compact CR manifolds. This is a joint work with Chin-Yu Hsiao.</div><div style="margin:2px 0px 0px"></div></div><div dir="ltr"><div dir="auto"><br></div><div dir="auto"></div><div dir="auto"><u><b>Information to attend in room 3014</b></u></div><div dir="auto">The seminar will take place in room 3014, at the building U5-Ratio, Università degli Studi di Milano Bicocca.</div><div dir="auto"><br></div><div dir="auto"></div><div dir="auto"><u><b>Information to attend online</b></u></div><div dir="auto"><table style="width:500px"><tbody><tr><td style="color:rgb(0,0,0);font-family:Arial;font-size:12px;font-weight:bold;line-height:24px"><b>Join from the meeting link</b></td></tr><tr style="margin:0px"><td style="font-family:Arial;font-size:14px;line-height:24px;max-width:500px;word-break:break-all"><a href="https://unimib.webex.com/unimib/j.php?MTID=md67c08b381ecba355e7dbbf5182fef4a" target="_blank" style="color:rgb(0,94,125);text-decoration-line:none;line-height:24px">https://unimib.webex.com/unimib/j.php?MTID=md67c08b381ecba355e7dbbf5182fef4a</a></td></tr></tbody></table><table><tbody><tr style="line-height:20px"><td style="height:20px"> </td></tr></tbody></table><table style="width:auto"><tbody><tr><td style="color:rgb(0,0,0);font-family:Arial;font-size:12px;font-weight:bold;line-height:24px"><b>Join by meeting number</b></td></tr><tr><td style="font-family:Arial;color:rgb(51,51,51);font-size:14px;line-height:22px"><span dir="ltr">Meeting number (access code):</span> <span dir="auto">2743 576 9398</span></td></tr><tr><td style="font-family:Arial;color:rgb(51,51,51);font-size:14px;line-height:22px">Meeting password: aCdBmV6rV73 <span dir="auto">(22326867 from phones)</span></td></tr></tbody></table><table><tbody><tr style="line-height:20px"><td style="height:20px"> </td></tr></tbody></table></div><div dir="auto"><span style="background-color:transparent;color:rgb(0,0,0);font-family:arial,sans-serif;white-space:pre-wrap">Please feel free to forward this information to anyone who might be interested.</span><br></div><div dir="auto"><div dir="auto"><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(0,0,0);background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;font-variant-alternates:normal;vertical-align:baseline;white-space:pre-wrap">
