Webb23 juni 2024 · We apply a singularity analysis to investigate the integrability properties of the gravitational field equations in Weyl Integrable Spacetime for a spatially flat Friedmann–Lemaître–Robertson–Walker background spacetime induced by an ideal gas. We find that the field equations possess the Painlevé property in the presence of the … Webb4 juni 1998 · In this paper we investigate the Painlevé property for partial differential equations. By application to several well‐known partial differential equations (Burgers, KdV, MKdV, Bousinesq, higher‐order KdV and KP equations) it is shown that consideration of the ‘‘singular manifold’’ leads to a formulation of these equations in terms of the ‘‘Schwarzian …

The common name for a group of six special ordinary differential equations of the type. where $ R $ is a rational function in $ w ^ \prime $ and $ w $ and an analytic function in $ z $. Any such equation having only fixed singular points (cf. Movable singular point) can be reduced to one out of 50 canonical equations. chinese character writing sheet pdf
Bäcklund transformation and the Painlevé property - AIP Publishing
Webb2 feb. 2024 · In this paper, the Painlevé integrable property of the (1 + 1)-dimensional generalized Broer–Kaup (gBK) equations is first proven. Then, the Bäcklund transformations for the gBK equations are derived by using the Painlevé truncation. Based on a special case of the derived Bäcklund transformations, the gBK equations are … Webb4 juni 1998 · The Caudrey–Dodd–Gibbon equation is found to possess the Painlevé property. Investigation of the Bäcklund transformations for this equation obtains the … Webb17 feb. 2009 · We show that the low-growth requirements lead, in the case of the discrete Painlevé equations, to exactly the same results as singularity confinement. The analysis of linearisable mappings shows that they have special growth properties which can be used in order to identify them. chinese charger
