Translated from the unique Russian variation of 1987 (Nauka, Moscow), this quantity offers with the speculation of multi-frequency oscillations as a movement of a dynamical method which describes a recurrent trajectory on an invariant toroidal manifold of the method. during this approach, the invariant toroidal manifo

In this monograph, group-theoretical methods are used to construct a method of hadrons and qualitatively describe the homes of chemical substances. This serves as a supplement to numerically and nearly clear up the many-electron Schrödinger equation, so that it will comprehend the habit of chemical parts. along with common conception, particular effects are in comparison with experimentally measured chemical homes.

Few have had particularly as a lot effect in either the academy and on this planet of theatre construction as Richard Schechner. For greater than 4 a long time his paintings has challenged traditional definitions of theatre, ritual and function. while this seminal assortment first seemed, Schechner's strategy used to be not just novel, it used to be progressive: drama is not only whatever that happens on degree, yet whatever that occurs in lifestyle, packed with that means, and on many alternative degrees. inside of those pages he examines the connections among Western and non-Western cultures, theatre and dance, anthropology, ritual, functionality in lifestyle, rites of passage, play, psychotherapy and shamanism.

This number of articles includes contributions from some of Werner Leinfellner's many buddies and co-workers. a few of them are former scholars of Werner's. Others have been colleagues of his at numerous American and eu universities. extra, a few have come to understand Werner via his study, his long-standing editorship of conception and Deci sion and his wide participation in foreign meetings and congresses. the subsequent articles are new to this quantity. The components lined are these within which Werner maintains to play an energetic specialist position. we provide them as a tribute to the various and multi-faceted contributions to the clinical firm for which Werner Leinfellner is so well known. We think one of these festschrift to be becoming and lengthy past due. end result of the breadth of Werner's expert institutions, it used to be tricky to choose representatives from between his many spheres of effect. We ask for forgiveness to the numerous students who couldn't be in cluded due to time and house concerns. ultimately, we want to exhibit appreciation to Dean John Guilds of the college of Arkansas for offering monetary aid early on within the evolution of this venture, to Jennifer Bauman for her bravura functionality in copy-editing the manuscripts, and to our writer at Reidel for bringing this quantity to press.
