Abstract
e investigate the coherent focusing in a weak magnetic field of a two-dimensional hole gas realized in a semiconductor heterostructure. By use of a simple model, we study how the coherence effects displayed by ballistic conduction electrons are modified if warped and nonparabolic bands are taken into account. We
