Trans-Series Asymptotics of Solutions to the Degenerate Painlevé III Equation: A Case Study

A one-parameter family of trans-series asymptotics as τ → ±∞ and τ → ±i∞ for solutions of the degenerate Painlevé III equation (DP3E), ′′(τ) = (′(τ))²/(τ) − ′(τ)/τ + 1/τ(−8ε(u(τ))² + 2) + ²/(τ), where ε ∈ {±1}, ∈ ℂ, and ∈ ℝ∖{0}, are parametrised in terms of the monodromy data of an associated firs...

description A one-parameter family of trans-series asymptotics as τ → ±∞ and τ → ±i∞ for solutions of the degenerate Painlevé III equation (DP3E), ′′(τ) = (′(τ))²/(τ) − ′(τ)/τ + 1/τ(−8ε(u(τ))² + 2) + ²/(τ), where ε ∈ {±1}, ∈ ℂ, and ∈ ℝ∖{0}, are parametrised in terms of the monodromy data of an associated first-order 2 × 2 matrix linear ODE via the isomonodromy deformation approach: trans-series asymptotics for the associated Hamiltonian and principal auxiliary functions and the solution of one of the σ-forms of the DP3E are also obtained. The actions of various Lie-point symmetries for the DP3E are derived.
