QCD sum rule calculation of the quark gluon condensate
The QCD sum-rule method is used to find the value of the quark--gluon condensate for massless quarks, (..mu..) = m/sup 2//sub 0/(..mu..), with ..mu.. = 1 GeV and m/sup 2//sub 0/ = 0.8 +- 0.16 GeV/sup 2/. The s-quark condensate is found to be approx. =0.5 (q = u,d).

title: The calculation of the leading ms corrections to the PCAC relation for the K-meson
abstract: We use the operator product expansion for the calculation of the s-quark mass correction to the K-meson PCAC relation. The leading m s correction gives a large (about 50%) contribution tothe standard PCAC relation. We obtain also the value of the SU(3) symmetry breaking parameter for the quark vacuum condensates γ =0.46.

title: On the universal relations for the prefactors in correlation functions of 1D quantum liquids
abstract: For various one-dimensional quantum liquids in the framework of the Luttinger model (bosonization) we establish the relations between the coefficients before the power-law asymptotics of the correlators (prefactors) and the formfactors of the corresponding local operators. The derivation of these relations in the framework of the bosonization procedure allows to substantiate the prediction for the formfactors corresponding to the low-lying particle-hole excitations. We also obtain the formulas for the summation over the particle-hole states corresponding to the power-law asymptotics of the correlators.

title: EXACT GROUND STATE OF THE GENERALIZED HUBBARD MODEL FOR A WIDE RANGE OF PARAMETERS
abstract: We present the exact ground-state wave function and energy of the generalized Hubbard model, subjected to the condition that the number of doubly-occupied sites is conserved for a wide physically relevant range of parameters. For one hole and one doubly-occupied site, the existence of the ferromagnetic ground state is proved which allows one to determine the critical value of the on-site repulsion corresponding to the point of metal–insulator transition.

title: CONSTRUCTION OF MONODROMY MATRIX IN THE F-BASIS AND SCALAR PRODUCTS IN SPIN CHAINS
abstract: We present in a simple terms the theory of the factorizing operator introduced recently by Maillet and Sanches de Santos for the spin-1/2 chains. We obtain the explicit expressions for the matrix elements of the factorizing operator in terms of the elements of the monodromy matrix. We use this results to derive the expression for the general scalar product for the quantum spin chain. We comment on the previous determination of the scalar product of Bethe eigenstate with an arbitrary dual state. We also establish the direct correspondence between the calculations of scalar products in the F-basis and the usual basis.

BETHE ANSATZ FOR NON-COMPACT GROUPS: THE PAIRING MODELS FOR BOSONS
We discuss the construction of the exactly solvable pairing models for bosons in the framework of the Quantum Inverse Scattering method. It is stressed that this class of models naturally appears in the quasiclassical limit of the algebraic Bethe ansatz transfer matrix. We propose the new pairing Hamiltonians for bosons, depending on the additional parameters. It is pointed out that the new class of the pairing models can be obtained from the fundamental transfer-matrix. The possible new application of the pairing models for confined bosons in the physics of helium nanodroplets is pointed out.

Model-space Brueckner-Hartree-Fock approach for asymmetric nuclear matter.
The model-space Brueckner-Hartree-Fock (BHF) approach of nuclear matter is extended to asymmetric nuclear matter. The energy per nucleon of bulk nuclear matter is calculated over a wide range of density and asymmetry parameter with both the Reid soft-core and the Paris nucleon-nucleon interactions. The results are compared to those calculated by using the usual BHF approach.
