DESCRIPTION:<p>This talk focuses on Laurent expansions of super lambda-len
 gths in a marked disk.&nbsp\; It is based on work in<br /><a href="https:/

 auth="NotApplicable" data-linkindex="8">https://arxiv.org/abs/2102.09143</
 a>\, which generalizes Schiffler's T-path formula\, and a recent sequel in
 &nbsp\;<a href="https://arxiv.org/abs/2110.06497" target="_blank" rel="noo
 pener noreferrer" data-auth="NotApplicable" data-linkindex="9">https://arx
 iv.org/abs/2110.06497</a>\, which gives an alternate combinatorial express
 ion in terms of double dimer covers on snake graphs. The latter generalize
 s an earlier interpretation of dimers on snake graphs for ordinary lambda 
 lengths defined with Schiffler and Williams.&nbsp\; For the case of super 
 lambda-lengths\, this is joint work with Ovenhouse and Zhang.</p>
