# q-Discrete Toda Molecule Equation

**Authors:** Kenji Kajiwara, Yasuhiro Ohta, Junkichi Satsuma

## Abstract
A q-discrete version of the two-dimensional Toda molecule equation is
proposed through the direct method. Its solution, B\"acklund transformation and
Lax pair are discussed. The reduction to the q-discrete cylindrical Toda
molecule equation is also discussed.
