Abstract
The formation of essentially nonlinear, time-dependent structures in the co mpressible advection problem is examined. Based on the Lagrangian descripti on, the influence of initial conditions on the emergence of new nonlinear s tructures is studied. Conditions leading to the formation of new regular, a s well as singular, collapse-type structures and wavelet structures in the density profile are presented. (C) 2001 American Institute of Physics.
