Elliptic Hall algebra on ${\mathbb{F}}_1$

We construct Hall algebra of elliptic curve over ${\mathbb{F}}_1$ using the theory of monoidal scheme due to Deitmar and the theory of Hall algebra for monoidal representations due to Szczesny. The resulting algebra is shown to be a specialization of elliptic Hall algebra studied by Burban and Schiffmann. Thus our algebra is isomorphic to the skein algebra for torus by the recent work of Morton and Samuelson.
