SEMINARI DI EQUAZIONI DIFFERENZIALI E APPLICAZIONI
Mercoledì 17 Aprile 2013 alle ore 12:15 in aula 2BC30 Annalisa Massaccesi (Università di Milano) terrà un seminario dal titolo "Currents with coefficients in a group and the Steiner Problem".
The Steiner problem consists in finding the shortest connected set including some fixed points; we show how to formulate it as a mass-minimization problem for 1-dimensional rectifiable currents with coefficients in a suitable normed group.
Thanks to the representation adopted for these currents, we can exploit the calibration method and we can analyse some examples. This is a joint work with A. Marchese.
Rif. Int. M. Bardi, C. Marchi, P. Mannucci
