The aim of the present paper is to analyse briefly the complicated references to musical composition in the work of Claude Lévi-Strauss. In his monumental tetralogy entitled Mythologiques, Lévi-Strauss considers the musical composition as a paradigm for structural analysis of myths. In this respect, the author compares Lévi-Strauss’ position with that of Pierre Schaeffer whose project of the “concrete music” is strongly criticised by Lévi-Strauss. In the second part of the text, Lévi-Strauss’ structural analysis of Wagner’s operas are examined, as well as the criticism ad dressed to Lévi-Strauss by Jean-Jacques Nattiez - universalist pretension and vagueness of the method based upon binary oppositions seems to represent weak points of Lévi-Strauss’ impressive effort to set new bases for human sciences. and Josef Fulka.
The destabilizing effect of four different types of multivalued conditions describing the influence of semipermeable membranes or of unilateral inner sources to the reaction-diffusion system is investigated. The validity of the assumptions sufficient for the destabilization which were stated in the first part is verified for these cases. Thus the existence of points at which the spatial patterns bifurcate from trivial solutions is proved.
