Title: A strictly convex and smooth Banach space with the Daugavet property
</p>
<p class="ql-ed">
Abstract <br />
<p>In this talk, we construct an equivalent norm on L_1[0,1], arbitrarily close to the usual L_1-norm, which is weakly midpoint locally uniformly rotund and Gâteaux smooth, and whose dual norm has the Daugavet property. In particular, we obtain a strictly convex and smooth Banach space with the Daugavet property, thereby solving a longstanding open problem in the field.</p><p><br></p><p>This is a joint work with Jaan Kristjan Kaasik and Yoël Perreau from Tartu University, Estonia.</p><p><br></p><p>PLEASE NOTE THE UNUSUAL TIME: The talk starts 11:15.</p>
