Nonlinear superconformal symmetry of a fermion in the field of a Dirac monopole

open access: yes, 2003
We study a longstanding problem of identification of the fermion-monopole symmetries. We show that the integrals of motion of the system generate a nonlinear classical Z_2-graded Poisson, or quantum super- algebra, which may be treated as a nonlinear ...

On the asymptotics of the $\alpha$-Farey transfer operator

open access: yes, 2014
We study the asymptotics of iterates of the transfer operator for non-uniformly hyperbolic $\alpha$-Farey maps. We provide a family of observables which are Riemann integrable, locally constant and of bounded variation, and for which the iterates of the ...

Hybrid spherical approximation

open access: yes, 2014
In this paper a local approximation method on the sphere is presented. As interpolation scheme we consider a partition of unity method, such as the modified spherical Shepard's method, which uses zonal basis functions (ZBFs) plus spherical harmonics as ...

Эффективный нерезолютивный вывод для ограниченного исчисления хорновских дизъюнктов [PDF]

open access: yes, 2008
Представлен механизм, обеспечивающий логический вывод для систем логического программирования типа Пролог. Предлагаемый подход отличается от стандартного метода резолюций и опирается на обратную стратегию в стиле С.Ю. Маслова.

Finding All Nash Equilibria of a Finite Game Using Polynomial Algebra

open access: yes, 2006
The set of Nash equilibria of a finite game is the set of nonnegative solutions to a system of polynomial equations. In this survey article we describe how to construct certain special games and explain how to find all the complex roots of the ...

Continuous Family of Invariant Subspaces for R-diagonal Operators

open access: yes, 2001
We show that every R-diagonal operator x has a continuous family of invariant subspaces relative to the von Neumann algebra generated by x. This allows us to find the Brown measure of x and to find a new conceptual proof that Voiculescu's S-transform is ...

Doubling measures on uniform Cantor sets

open access: yes, 2014
We obtain a complete description for a probability measure to be doubling on an arbitrarily given uniform Cantor set. The question of which doubling measures on such a Cantor set can be extended to a doubling measure on [0; 1] is also ...
