DE LA CRUZ GUERRERO, Richard Alexander; JUAJIBIOY OTERO, Juan Carlos  and  RENDON ARBELAEZ, Leonardo. Global weak solutions for a 2 x 2 balance non-symmetric system of Keyfitz-Kranzer type. Ciencia en Desarrollo [online]. 2017, vol.8, n.1, pp.29-33. ISSN 0121-7488.

In this paper we consider the Cauchy problem for a particular non-symmetric Keyfitz-Kranzer type system, by using the vanishing viscosity method coupled with the compensated compactness method we get global bounded entropy weak solutions. The main difficulty is to get uniformly bounded estimates on the viscosity method and in this paper is studied.

Keywords : Hyperbolic system; global weak solutions; non-symmetric system; Keyfitz-Kranzer type.
