00925njm 22002777a 4500 dc Díaz Díaz, Jesús Ildefonso author Véron, Laurent author 1983 The authors consider first-order equations in "conservation laws'' form perturbed by a semilinear nonlinearity of monotone type. The known existence and uniqueness results for conservation laws—results due to Kruzhkov—are easily adapted to this situation and some qualitative properties of the solutions are discussed. 0022-2518 10.1512/iumj.1983.32.32025 https://hdl.handle.net/20.500.14352/64670 http://www.iumj.indiana.edu/IUMJ/FULLTEXT/1983/32/32025 Existence theory and qualitative properties of the solutions of some first order quasilinear variational inequalities.
