%0 Journal Article %T On some regularity and nonregularity results for solutions to parabolic systems %A Jana Star¨˘ %A Old£żich John %J Le Matematiche %D 2000 %I University of Catania %X A short survey of recent results on smoothness of weak solutions to parabolic systems with nonsmooth coefficients in olane is given. Moreover, for space dimensions nge 3 and any closed subset F in R^n we construct a linear parabolic system with bounded measurable coefficients and its solution which is essentially discontinuous on F and essentially continuous on R^nF. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/308
