q-calculus, also known under the name of h-calculus, has found wide applications in many areas of mathematics. In this paper we provide for a basic financial option pricing application where we try to rationalize the use of a q-derivative. We provide for a brief discussion on how the value of q can be an indicator of either the use (or not the use) of the risk free rate of interest in the option pricing partial differential equation." /> Quantum calculus (q-calculus) and option pricing - Haven Emmanuel | sdvig press
