Abstract

A new approach is developed for solving spectral problems for operators with continuous spectrum, which consists in the integral transform of the problem by using coherent Schwartz distributions. The constructed family of coherent distributions is a complete analogue of the family of ordinary coherent states. More precisely, it satisfies all Gazeau–Klauder axioms satisfied by the usual coherent states. But in contrast to the coherent states belonging to the point spectrum of the annihilation operator (or operators), the coherent distributions belong to the continuous spectrum of some Hermitian operators. Therefore, the coherent distributions work better than the coherent states as the kernel of the integral representation of generalized eigenfunctions of operators with continuous spectrum. In this work, this approach is demonstrated with an example of solving a basic problem of quantum mechanics, i.e., the problem of the continuous part of the spectrum of the Hamiltonian of the hydrogen atom.

6. Coherent transforms and irreducible representations corresponding to complex structures on a cylinder and on a torus

Author

Karasev, M. V. and Novikova, E. M.

Subjects
Mathematics - Quantum Algebra
Abstract

We study a class of algebras with non-Lie commutation relations whose symplectic leaves are surfaces of revolution: a cylinder or a torus. Over each of such surfaces we introduce a family of complex structures and Hilbert spaces of antiholomorphic sections in which the irreducible Hermitian representations of the original algebra are realized. The reproducing kernels of these spaces are expressed in terms of the Riemann theta-function and its modifications. They generate quantum K\"ahler structures on the surface and the corresponding quantum reproducing measures. We construct coherent transforms intertwining abstract representations of an algebra with irreducible representations, and these transforms are also expressed via the theta-function., Comment: 21 pages, Amstex-file

33. [Protective efficacy of combined administration of the multicomponent vaccine and the immunomodulator myelopid in experimental infections in mice].

Abstract

The influence of myelopid (MP) on the protective activity of polycomponent vaccine VP-4 prepared from the antigens of opportunistic bacteria was studied on experimental infections of mice, caused by Klebsiella pneumoniae, Salmonella typhimurium and Staphylococcus aureus. In staphylococcal and Klebsiella infections the joint administration of vaccine VP-4 and MP produced more pronounced protective effect than each of these preparations, introduced alone. The protective action of vaccine VP-4 was specially enforced by MP in cases of local staphylococcal infection. Recommendations on the joint use of two or more immunomodulating agents are possible only on the basis of the experimental substantiation of their effect in definite infections.

Abstract

The authors review their 5-year experience with the work of the women's diagnostic department for recognition of cancer and precancer of the mammary gland. The efficacy of the activities of this diagnostic department is believed to be determined by two main factors: 1) proper organization of its activity and 2) its close contacts with an oncologist of the polyclinic.
