RT Journal Article T1 Blow-up in nonlinear models of extended particles with confined constituents A1 Fernández-Rañada, Antonio A1 Álvarez Alonso, Amador AB It is shown that the indefinite character of the charge in classical models of extended particles with confined constituents is a serious handicap since infinite amounts of positive and negative charge can be emitted in some solutions, causing a blow-up in finite time.
