Summary Gestalt Theoretical Psychotherapy, in the broader sense of the term, has developed in various forms on both sides of the Atlantic since the 1920s. Gestalt Theoretical Psychotherapy, in the narrower sense of the term, came into being in the second half of the 1970s in German-speaking countries. In Austria, it is a state-approved, independent scientific psychotherapy method since 1995, and an integrative psychotherapeutic approach based on the Gestalt theory of the Berlin School. With reference to this comprehensive, consistent, scientific (...) theory, this article presents the basic concepts of therapeutic practice in the field of Gestalt psychotherapy. Starting from the overarching whole to the parts, the paper first examines the concept of therapeutic relationship and therapeutic attitude, and then describes the basic principles of the practical design of the therapeutic process.

The "Essentials of Gestalt Theoretical Psychotherapy" offer for the first time in English an insight into the guiding ideas of this integrative psychotherapy method, which is consistently anchored in Gestalt psychology (and in this respect also differs substantially from most streams of Gestalt therapy, with which it should not be confused). The anthology includes ten contributions by authors from Austria, Italy, Germany and the USA. These deal with fundamental questions and concepts of any psychotherapy: The role and meaning of consistency (...) in practical life and in psychotherapy; the question of human epistemic possibilities and an epistemology appropriate for psychotherapy; the personality theory of Gestalt Theoretical Psychotherapy; the basic principles of therapeutic relationship and practice; the role of emotions in the example of phenomenal causality of feelings; the task of diagnostics in Gestalt Theoretical Psychotherapy; a clinical example related to anorexia; Gestalt psychological viewpoints for therapy progress; the role of relational determination in intrapsychic and interpersonal experience.

In the framework of the rigged Hilbert space, unstable quantum systems associated with first-order poles of the analytically continued S-matrix can be described by Gamow vectors which are generalized vectors with exponential decay and a Breit-Wigner energy distribution. This mathematical formalism can be generalized to quasistationary systems associated with higher-order poles of the S-matrix, which leads to a set of Gamow vectors of higher order with a non-exponential time evolution. One can define a state operator from the set of higher-order (...) Gamow vectors which obeys the exponential decay law. We shall discuss to what extent the requirement of an exponential time evolution determines the form of the state operator for a quasistationary microphysical system associated with a higher-order pole of the S-matrix.

The physical motivations for the dynamical group are presented and it is shown how Barut's mathematical speculations were combined with the idea of an elementary length to provide group theoretical models of relativistic extended objects. Then the simplest nonrelativistic and relativistic models are described.

A quantum theory combining an irreversible time evolution semigroup with a time reversal operator is presented.
