Example of shock wave in unstaible medium: The focusing nonlinear Schrodinger equation
Dissipationless shock waves in modulational unstable one-dimensional medium
are investigated on the simplest example of integrable focusing nonlinear
Schr\''odinger (NS) equation. Our approach is based on the construction of
special exact solution of the Whitham-NS system, which ''partially saturates''
the modulational instability.Comment: 4 pages, LaTEX, version 2.09, submitted to Phys. Lett.
