Approximation in Sobolev Spaces between two manifolds and homotopy groupsh maps between .. and .. to be dense in ..(.., ..). This condition can be simply stated in terms of homotopy groups, and is π.(..)= 0. In cases where such a condition does not hold, we show that we can approximate maps in ..(.., ..) by maps smooth except on a singular set which has a simple shape. W

Evolution equations with discontinuous nonlinearities and non-convex constraints14) ), which are studied in propositions (3.2) and (3.3). This fact resembles the situation in the regular setting: a sufficent condition for the intersection of two manyfolds .. and .. to be a manyfold is the non tangency between .. and ...
