Open AccessGraded Symmetry Algebras of Time-Dependent Evolution Equations and Application to the Modified KP Equations
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 KP equations are taken as an...

Open AccessSymmetries of the Classical Integrable Systems and 2-Dimensional Quantum Gravity: a ‘Map’
We draw attention to the connections recently established by others between the classical integrable KdV and KP hierarchies in 1 + 1 and 2 + 1 dimensions respectively and the matrix models which relate to the ...
