SUMMARY:Seminar, Chunlan Jiang (Hebei Normal University), Similarity Invariants of Geometric Operators
DESCRIPTION:<p>	<drupal-media data-entity-type="media" data-entity-uuid="1e0b4087-39cb-4fde-87a8-aeeefe72b780" alt="Chunlan Jiang" data-view-mode="hwp_small"></drupal-media></p><p>	<span><strong>Title</strong>：Similarity Invariants of Geometric Operators</span></p><p>	<br><span><strong>Abstract</strong>: In 1978, I.M.Cowen and R.G .Douglas introduced a class of geometric operators in a Grassmann manifold. In their influential paper they give a unitary invariant involving geometric ideas, such as curvature, that completely classifies these operators. At the same time they ask: Can one use geometric ideas to characterize completely the similarity invariants of geometric operators? We give a partial answer to this question. We show that the curvature and second fundamental form completely characterize the similarity invariants for a norm dense class of all geometric operators. </span></p><div class="yj6qo">	 </div><div class="adL">	 </div><p>	 </p>
