In particular, understanding dg-categories is crucial for formulating and interpreting homological mirror symmetry.</div>
<div class="v1v1pre">
<p>In this talk, I will present our approach to the homotopy theory of dg-categories by establishing a cofibration structure, which can be viewed as a half-model structure. This structure enables a combinatorial description of derived constructions and offers computational advantages. This is joint work with Sangjin Lee (arXiv:2109.03411 and arXiv:2405.03258). Some key applications of our approach, particularly in symplectic and contact geometry, include:</p>
<ul>
<li>Combinatorial description of homotopy colimits of dg categories, which gives a local-to-global formula computing wrapped Fukaya categories of symplectic manifolds,</li>
<li>Local-to-global construction of functors between wrapped Fukaya categories that are induced by symplectomorphisms,</li>
<li>A simple description of internal Hom and Hochschild cohomology of dg-categories. This ongoing work aims to provide useful tools for addressing the Weinstein conjecture, which concerns the existence of periodic orbits of Reeb vector fields.</li>
</ul>
<p>I plan to cover as much of this content as time permits, and according to the audience's interest.</p>
