Graded Symmetry Algebras of Time-Dependent Evolution Equations and Application to the Modified KP equations
W. X. Ma, R. K. Bullough, P. J. Caudrey
By starting from known graded Lie algebras, including Virasoro algebras, new kinds of time-dependent evolution equations are found possessing graded symmetry algebras. The modified…

Time-Dependent Symmetries of Variable-Coefficient Evolution Equations and Graded Lie Algebras
W. X. Ma, R. K. Bullough, P. J. Caudrey +1
Polynomial-in-time dependent symmetries are analysed for polynomial-in-time dependent evolution equations. Graded Lie algebras, especially Virasoro algebras, are used to construct…
