TITLE: Viennot-type geometric description for dual RSK correspondence?
QUESTION [10 upvotes]: Is a geometric construction of the dual RSK correspondence along the lines of Viennot's "light and shadows construction" written up somewhere? This is a bijective correspondence between 0-1 matrices and pairs of SSYT with mutually transpose shapes.

REPLY [3 votes]: It's all written up rather nicely in Heather Dornom's Honours thesis from 2005. She gives a version of the matrix ball construction that works in these cases and also explains growth models for the RSK correspondence and its dual.
