| Outline of Final Research Achievements |
The purpose of this study is to understand discontinuous solutions of partial differential equations that come from secondary recovery techniques: injecting water and gas (air or CO2 ) for the extraction of petroleum in a oil reservoir which is contained in porous rock formations. Based on these mathematical studies, global behavior of shock waves in mixed gas and ionized gas is studied, where the construction and study of entropy functions play a crucial role.
