[Matteo Novaga]

Segnalo a tutti gli interessati che venerdi' 9 ottobre,
alle ore 15, nell'Aula Magna del Dipartimento di Matematica,
il Prof. Jeffrey Rauch (University of Michigan)
terra' un seminario dal titolo:

               Earnshaw's Theorem in Electrostatics

Abstract:

Earnshaw's Theorem. (Trans. Cambridge Phil. Soc(1842)).
A test charge in an electrostatic field can never be in a position of 
stable equilibrium. This theorem is still not proved but much progress has 
been made. Some seemingly more difficult results asserted by Maxwell have 
been proved.
