On the geometry of a 4-dimensional extension of a -Painlevé I equation with symmetry type
Alexander Stokes, Tomoyuki Takenawa, Adrian Stefan Carstea
We present a geometric study of a four-dimensional integrable discrete dynamical system which extends the autonomous form of a -Painlevé I equation with symmetry of type $A_1^{…
