%0 Journal Article %A Fernández-Rañada, Antonio %A Álvarez Alonso, Amador %T Blow-up in nonlinear models of extended particles with confined constituents %D 1988 %@ 0556-2821 %U https://hdl.handle.net/20.500.14352/59018 %X 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. %~
