Shannon Wavelets for the Solution of Integrodifferential Equations

open access: yesMathematical Problems in Engineering, Volume 2010, Issue 1, 2010., 2010
Shannon wavelets are used to define a method for the solution of integrodifferential equations. This method is based on (1) the Galerking method, (2) the Shannon wavelet representation, (3) the decorrelation of the generalized Shannon sampling theorem, and (4) the definition of connection coefficients.

Kinetic model of three component, weakly ionized, collisional plasma with a beam of neutral particles

open access: yes, 1999
Kinetic model of three component, weakly ionized, collisional plasma with a beam of neutral particles is developed. New dispersion relations for linear perturbations are derived and analyzed in various limiting cases.Comment: 5 pages, RevTex style, no ...

Symmetry group analysis and invariant solutions of hydrodynamic‐type systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 10, Page 487-534, 2004., 2004
We study point and higher symmetries of systems of the hydrodynamic type with and without an explicit dependence on t, x. We consider such systems which satisfy the existence conditions for an infinite‐dimensional group of hydrodynamic symmetries which implies linearizing transformations for these systems.

Open membranes, ribbons and deformed Schild strings

open access: yes, 2004
We analyze open membranes immersed in a magnetic three-form field-strength $C$. While cylindrical membranes in the absence of $C$ behave like tensionless strings, when the $C$ flux is present the strings polarize into thin membrane ribbons, locally ...

Lower Bound of the Complexity of Functions over Finite Field of Order 4 in the Class of Polarized Polynomials

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
The representations, including polynomial, of functions over final fields have been actively investigated. The complexity of such representations is the main stream of research.

Symmetries and Interaction coefficients of Kelvin waves

open access: yes, 2010
We considered symmetry restriction on the interaction coefficients of Kelvin waves and demonstrated that linear in small wave vector asymptotic is not forbidden, as one can expect by naive reasoning.Comment: 4 pages, submitted to J.

Relativistic Charge Form Factor of the Deuteron [PDF]

open access: yes, 1997
Relativistic integral representation in terms of experimental neutron-proton scattering phase shifts alone is used to compute the charge form factor of the deuteron $G_{Cd}(Q^2)$.

Force-velocity relation and density profiles for biased diffusion in an adsorbed monolayer

open access: yes, 2000
In this paper, which completes our earlier short publication [Phys. Rev. Lett. 84, 511 (2000)], we study dynamics of a hard-core tracer particle (TP) performing a biased random walk in an adsorbed monolayer, composed of mobile hard-core particles ...

USLV: Unspanned Stochastic Local Volatility Model [PDF]

open access: yes, 2013
We propose a new framework for modeling stochastic local volatility, with potential applications to modeling derivatives on interest rates, commodities, credit, equity, FX etc., as well as hybrid derivatives.

A Real Business Cycle Model with Changing Sentiments [PDF]

open access: yes
In this paper the modification of the real business cycles model in which risk aversion parameter of agents’ utility function follows bivariate markov chain is developed and estimated using simulated VAR. The model’s ability to replicate properties of US
