• Singular exponent
• Oscillatory traveling waves
• Polytropic filtration equation
• Generalized Fisher-KPP sources

The polytropic filtration equation with generalized Fisher-KPP sources is considered. We will show that the equation may have finite times oscillatory traveling waves, and try to give a complete classification by virtue of a singular exponent in the source according to the finiteness of the oscillatory times of traveling waves.
