Acoustic holograms can provide three-dimensional images of internal organs without surgery or dangerous

By using a particular geometric problem as a starting point the authors guide the reader into the subject. As such it ideally serves as preparation and as

The proof presented here uses the language of Lefschetz fibrations and pencils, thus it include

Anharmonic Interactions, account only quadratic terms of the crystal potential. This “harmonic” approximation corresponds to the assumption that the vibrational excitation of the crystal can be rigorously separated into a set of independent and non-interacting phonons, each having an infinite lifetime.
