Full characterisation of Painlevé V asymptotics and nonlinear monodromy-Stokes structure

Shun Shimomura

For a generic Painlevé V equation we characterise all the asymptotics in a right half plane near the point at infinity, that is, we find classified explicit solutions that are, by…

Elliptic asymptotic representation of the fifth Painlevé transcendents

Shun Shimomura

For the fifth Painlevé transcendents an asymptotic representation by the Jacobi -function is presented in cheese-like strips along generic directions near the point a…

Two error bounds of the elliptic asymptotics for the fifth Painlevé transcendents

Shun Shimomura

For the fifth Painlevé equation it is known that a general solution is represented asymptotically by an elliptic function in cheese-like strips near the point at infinity. We pres…

Elliptic asymptotics for the complete third Painlevé transcendents

Shun Shimomura

For a general solution of the third Painlevé equation of complete type we show the Boutroux ansatz near the point at infinity. It admits an asymptotic representation in terms of t…

Kapaev's global asymptotics of the fourth Painlevé transcendents. Elliptic asymptotics

Shun Shimomura

For the fourth Painlevé transcendents we derive elliptic asymptotic representations, which were announced by late Professor Kapaev without proofs. Then we newly obtain related res…

Explicit error term of the elliptic asymptotics for the first Painlevé transcendents

Shun Shimomura

For the first Painlevé transcendents Kitaev established an asymptotic representation in terms of the Weierstrass pe-function in cheese-like strips near the point at infinity. We p…
