The Formation of Tree Leaves
Abstract: Tree leaves have diverse and elaborate leaf venation
patterns and shapes. It is interesting to understand the mathematics
behind it. In this talk, I am going to provide a mathematical model to
formulate leaf venation patterns as well as their shapes. In the
model, cells aggregated in a way to build an efficient transport
system for leaf. The efficient transport system of a tree leaf build
here is a modified version of optimal transport paths, which are used
to study the phenomenon of ramifying structures in mass
transportation. Some computer visualization of tree leaves will be
provided at the end of the talk. These figures resemble many tree
leaves (like maples) well.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
