  • A generalization of an extended stochastic integral 
    Albeverio, S.; Berezansky, Yu.M.; Tesko, V.A. (Український математичний журнал, 2007)
    We propose a generalization of an extended stochastic integral in the case of integration with respect to a wide class of random processes. In particular, we obtain conditions for the coincidence of the considered ...
  • Algebras of Unbounded Operators over the Ring of Measurable Functions and Their Derivations and Automorphisms 
    Albeverio, S.; Ayupov, Sh.A.; Zaitov, A.A.; Ruziev, J.E. (2009)
    In the present paper derivations and *-automorphisms of algebras of unbounded operators over the ring of measurable functions are investigated and it is shown that all Lº-linear derivations and Lº-linear *-automorphisms ...
  • Approximation of general zero-range potentials 
    Albeverio, S.; Nizhnik, L.P. (Український математичний журнал, 2000)
    A norm resolvent convergence result is proved for approximations of general Schrodinger operators with zero-range potentials. An approximation of the δ’-interaction by nonlocal non-Hermitian potentials (without a renormalization ...
  • Infinite systems of stochastic differential equations and some lattice models on compact Riemannian manifolds 
    Albeverio, S.; Daletskii, A.Yu.; Kondrat’ev, Yu.G. (Український математичний журнал, 1997)
    Stochastic dynamics associated with Gibbs measures on an infinite product of compact Riemannian manifolds is constructed. The probabilistic representations for the corresponding Feller semigroups are obtained. The uniqueness ...
  • Singularly perturbed self-adjoint operators in scales of Hilbert spaces 
    Albeverio, S.; Kuzhel, S.; Nizhnik, L. (Український математичний журнал, 2007)
    Finite rank perturbations of a semi-bounded self-adjoint operator A are studied in the scale of Hilbert spaces associated with A. A concept of quasi-boundary value space is used to describe self-adjoint operator realizations ...
