Separation of variables and explicit theta-function solution of the classical Steklov--Lyapunov systems: A geometric and algebraic geometric background
Fedorov, Yuri; Basak Gancheva, Inna (2009-11)
Report de recerca
Accés obertAbstract The paper revises the separation of variables and explicit integration of the classical Steklov{ Lyapunov systems, which was ¯rst made by F. KÄotter in 1900. Namely, we give a geometric interpretation of the ... -
Sigma-function solution to the general Somos-6 recurrence via hyperelliptic Prym varieties
Fedorov, Yuri; Hone, Andy (Oxford University Press, 2016-09-09)
Article
Accés obertWe construct the explicit solution of the initial value problem for sequences generated by the general Somos-6 recurrence relation, in terms of the Kleinian sigma-function of genus 2. For each sequence there is an associated ... -
Steklov-Lyapunov type systems
Bolsinov, A. V.; Fedorov, Yuri (2003)
Article
Accés obertIn this paper we describe integrable generalizations of the classical Steklov– Lyapunov systems, which are defined on a certain product so(m) × so(m), as well as the structure of rank r coadjoint orbits in so(m)×so(m). ... -
The hydrodynamic Chaplygin sleigh
Fedorov, Yuri; García Naranjo Ortiz de la Huerta, Luis Constantino (2010)
Article
Accés obertWe consider the motion of rigid bodies in a potential fluid subject to certain nonholonomic constraints and show that it is described by Euler–Poincar´e– Suslov equations. In the two-dimensional case, when the constraint ... -
The motion of the 2D hydrodynamic chaplygin sleigh in the presence of circulation
Fedorov, Yuri; García Naranjo, Luis C.; Vankerschaver, Joris (2013-03)
Article
Accés obertWe consider the motion of a planar rigid body in a potential two-dimensional flow with a circulation and subject to a certain nonholonomic constraint. This model can be related to the design of underwater vehicles. ... -
The Picard-Fuchs equations for complete hyperelliptic integrals of even order curves, and the actions of the generalized Neumann system
Fedorov, Yuri; Pantazi, Chara (2014-03-01)
Article
Accés obertWe consider a family of genus 2 hyperelliptic curves of even order and obtain explicitly the systems of 5 linear ordinary differential equations for periods of the corresponding Abelian integrals of first, second, and third ... -
The sigma function over a family of curves with a singular fiber
Fedorov, Yuri; Komeda, Jiyro; Matsutani, Shigeki; Previato, Emma; Aomoto, Kazuhiko (2022-01-01)
Article
Accés restringit per política de l'editorialIn this paper we investigate the behavior of the sigma function over the family of cyclic trigonal curves Xs defined by the equation y3=x(x-s)(x-b1)(x-b2) in the affine (x, y) plane, for s ¿ De:= {s ¿ C¿s| < e}. We compare ...
