Abstract
For higher-order Kadomtsev–Petviashvili (KP) equations, the existence of explicitly time-dependent constants of motion is discussed. Generalizing the results for the ordinary KP equation, constants T(m)n,l polynomial in t are constructed for each lth order KP equation, for all n≥m (l−1)−1.Keywords
