Paper Abstract

Group velocity is typically defined as the derivative of the dispersion relation. However, we show that definition is not appropriate in general and is only applicable to wave equations with constant coefficients. We generalize the concept of group velocity and also show that in general one also has group acceleration. Explicit expressions are derived and examples are given.
