DESCRIPTION:<span>Co-author: Antonio Sartori		(University of Freiburg)    
     <br></span><br>In seminal work\, Cautis-Kamnitzer-Morrison  gave a dia
 grammatic presentation\, via a so-called  web calculus\, of the category o
 f quantum gln modules tensor generated  by the exterior powers. Their nove
 l observation was that a classical tool  from representation and invariant
  theory\, known as  skew Howe duality\, can be quantized and used to const
 ruct the corresponding diagrammatic presentation. <br><br>The work of Caut
 is-Kamnitzer-Morrison was then  extended to various other instance (and ev
 en categorified)\, but all of these have in common that they stay in type 
 A. <br><span><br>In this talk I will describe the first steps towards  gen
 eralizing Cautis-Kamnitzer-Morrison&#39\;s results to other types\, where 
 several new features (or flaws?) appear.</span>
