On the crystal limit of the q-difference sixth Painlevé equation

Nalini Joshi, Pieter Roffelsen

We consider the Riemann-Hilbert correspondence associated with the $q$ -difference sixth Painlevé equation in the crystal limit, i.e. $q \to 0$ , and show two main results. Fi…

Segre surfaces and geometry of the Painlevé equations

Nalini Joshi, Marta Mazzocco, Pieter Roffelsen

In this paper, we consider a six parameter family of affine Segre surfaces embedded in $C^{6}$ . For generic values of the parameters, this family is associated to the $q$ -dif…

Exponentially-improved asymptotics for $q$ -difference equations: $_{2} ϕ_{0}$ and $q P_{I}$

Nalini Joshi, Adri Olde Daalhuis

Usually when solving differential or difference equations via series solutions one encounters divergent series in which the coefficients grow like a factorial. Surprisingly, in the…
