چکیده
A problem of density matrix determination in terms of the given angular distribution of decay products is considered. In the first part of this paper (Section III) a quantum system, described by density matrix, has been considered. In this the density matrix was diagonal with respect to orbital quantum numbers and the state was mixed only partially. Now we will consider the process X → 0 + 0, where initial state is described by the density matrix ρ, for which we do not assume any other properties except hermitity and positive definiteness. The angular distribution is given by the expression

A problem of amplitude reconstruction in terms of the given angular distribution is considered. Solution of this problem is not unique. A class of amplitudes, correspondent to one and the same angular distribution, forms a region in projection onto a finite set of spherical harmonics. An explicit parametrization of a boundary of the region is obtained. A shape of the region of ambiguities is st...

Noncritical strings in the " coupling constant " phase space and bosonic string in the affine-metric curved space are dissipative systems. But the quantum descriptions of the dissipative systems have well known ambiguities. We suggest some approach to solve the problems of this description. The generalized Poisson algebra for dissipative systems is considered.

We show that instantons violate a supersymmetric identity in a classically supersymmetric Higgs model with no massless fermions. This anomalous breaking arises because the correct perturbative expansion in the instanton sector is not supersymmetric. The attempt to construct a manifestly supersymmetric expansion generates infra-red divergences.

We use the methods of group theory to reduce the equations of motion of the CP 1 model in (2+1) dimensions to sets of two coupled ordinary differential equations. We decouple and solve many of these equations in terms of elementary functions, elliptic functions and Painlevé transcendents. Some of the reduced equations do not have the Painlevé property thus indicating that the model is not integ...
