SUMMARY: (...): Evolution of spoon-shaped networks
DESCRIPTION:: After defining a regular planar network of curves\, we study 
 its motion by curvature. In particular\, we focus on two model cases: we c
 onsider a regular embedded network composed by three curves with fixed end
 points (triod) and a regular embedded network composed by two curves\, one
  of which is closed (spoon)\, and we study their evolution by curvature. T
 he first one converges to the Steiner minimal connection between the three
  endpoints\, if the lengths of the three curves stay far from zero. In the
  second case we show that the maximal existence time depends only on the a
 rea enclosed in the initial loop. Moreover\, the closed curve becomes even
 tually convex and then shrinks homotetically to a point\, approaching the 
 shape of a Brakke spoon.[http://gecogedi.dimai.unifi.it/person/91/]
