A Categorical Model for the Geometry of Interaction
We consider the multiplicative and exponential fragment of linear logic (MELL) and give a Geometry of Interaction (GoI) semantics for it based on unique decomposition categories. ...

Redundancy of minimal weight expansions in Pisot bases
Abstract. Motivated by multiplication algorithms based on redundant number representations, we study representations of an integer n as a sum n = k εkUk, where the digits εk are ...
