<p class="MsoNormal"><b>Naoki Koseki (Liverpool) Symmetric products of dg categories and semi-orthogonal decompositions</b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>Abstract. </b>The notion of symmetric products of a dg category was introduced by Ganter and Kapranov. I will explain how a semi-orthogonal decomposition (SOD) of an original dg category induces an SOD on the symmetric products. This
is a generalization of the direct sum decomposition of the symmetric product of a direct sum of two vector spaces. The main application is the construction of various interesting SODs on the derived categories of the Hilbert schemes of points on surfaces. </p>
