On a Lagrangian Version of the Lagrangian Whitney Trick
Yanghyun Byun
Pages. 115-123     



We write down a formula for a model case by which the Lagrangian
Whitney trick is realized, that is, a process to remove a pair of
transverse intersection points of a Lagrangian immersion by a
homotopy through Lagrangian immersions. The formula gives a
homotopy with compact support assuming the model satisfies
so-called an area-capacity condition. An observation is made
regarding the application of the technique, which is more amusing
than significant in its nature.

2. The formula
3. On applications of the formula
