A Tau function for $q$ -Painlevé VI as a Fredholm determinant

Harini Desiraju, Pieter Roffelsen

We give an analytic construction of a tau function for the $q$ -difference sixth Painlevé equation ( $q$ PVI) as a Fredholm determinant through the general Riemann-Hilbert problem ass…

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…

On the monodromy manifold of $q$ -Painlevé VI and its Riemann-Hilbert problem

Nalini Joshi, Pieter Roffelsen

We study the sixth $q$ -difference Painlevé equation ( $q P_{VI}$ ) through its associated Riemann-Hilbert problem (RHP) and show that the RHP is always solvable fo…
