On phase, action and canonical conservation laws in kinematic-wave theory
Canonical equations of energy and momentum are constructed in the kinematic-wave theory of waves in a continuum. This is done in analogy with what is achieved in nonlinear continuum mechanics. The starting point is a generalized balance of wave action. The standard formulas are recovered when the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Canonical equations of energy and momentum are constructed in the kinematic-wave theory of waves in
a continuum. This is done in analogy with what is achieved in nonlinear continuum mechanics. The starting
point is a generalized balance of wave action. The standard formulas are recovered when the system follows
from the averaged-Lagrangian variational formulation of Whitham. |
