Newtonian perturbations and the Einstein–Yang–Mills-dilaton equations
Classical and Quantum Gravity, 2005Co-Authors: Todd A. OliynykAbstract:In this paper, we show that the problem of proving the existence of a Countable Number of solutions to the static spherically symmetric SU(2) Einstein–Yang–Mills-dilaton (EYMd) equations can be reduced to proving the non-existence of solutions to the linearized Yang–Mills-dilaton equations (lYMd) satisfying certain asymptotic conditions. The reduction from a nonlinear to a linear problem is achieved using a Newtonian perturbation-type argument.

Global existence of solutions to the Einstein-Yang-Mills-dilaton equations ∗
arXiv: General Relativity and Quantum Cosmology, 2002Co-Authors: Todd A. OliynykAbstract:We prove the existence of a Countable Number of solutions to the static spherically symmetric SU(2) Einstein-Yang-Mills-dilaton (EYMd) equations. Existence is established using a Newtonian limit type argument which shows that static spherically symmetric SU(2) Yang-Mills-dilaton solutions can be continued smoothly to EYMd solutions provided they satisfy certain fall off conditions.

markov chains with a Countable Number of possible states

1992Co-Authors: A N ShiryayevAbstract:The transition probabilities we are interested in are defined for all real t ≥ 0 and satisfy the relations

PURSUIT DIFFERENTIAL GAME PROBLEM WITH INTEGRAL AND GEOMETRIC CONSTRAINTS IN A HILBERT SPACE
Journal of the Nigerian Mathematical Society, 2020Co-Authors: J. Rilwan, A. J. BadakayaAbstract:We study pursuit differential game problem with Countable Number of pursuers and one evader. Control functions of some finite Number of pursuers are subject to integral constraints while that of the remaining pursuers and evader are subject to geometric constraint. Sufficient conditions for completion of pursuit in two different theorems are presented. Moreover, attainability domains and strategies of the players are also constructed. Furthermore, illustrative examples are given.

VALUE OF A DIFFERENTIAL GAME PROBLEM WITH MULTIPLE PLAYERS IN A CERTAIN HILBERT SPACE
Journal of the Nigerian Mathematical Society, 2017Co-Authors: A. J. BadakayaAbstract:We study differential game problem involving Countable Number of pursuers and one evader in the space l2. Players’ motion obey ordinary differential equations with integral constraints subjected to the control functions of the players. Termination time of the game is fixed. The payoff functional is the greatest lower bound of distances between pursuers and the evader when the game is terminated. Optimal strategies of the players are constructed and value of the game is found.

nDS - A white noise approach to linear stochastic systems
2009 International Workshop on Multidimensional (nD) Systems, 2009Co-Authors: Daniel Alpay, David LevanonyAbstract:We present a new approach to study linear stochastic systems, where randomness is also included in the transfer function. We use the white noise setting, and the systems input-output relation is given in terms of two convolutions. The Hermite transform allows to describe the results in terms of functions analytic in a Countable Number of variables.

An Interpolation Problem for Functions with Values in a Commutative Ring
arXiv: Functional Analysis, 2012Co-Authors: Daniel Alpay, Haim AttiaAbstract:It was recently shown that the theory of linear stochastic systems can be viewed as a particular case of the theory of linear systems on a certain commutative ring of power series in a Countable Number of variables. In the present work we study an interpolation problem in this setting. A key tool is the principle of permanence of algebraic identities.
