Penrose Instabilities and the Emergence of Rogue waves in Sasa-Satsuma equation
M. Pradeepa, N. Vishnu Priya, M. Senthilvelan
In this paper, we calculate the region of emergence of rogue waves in the Sasa-Satsuma equation by performing Penrose stability analysis. We consider Wigner-transformed Sasa-Satsum…
