Generalizing subdiffusive Black-Scholes model by variable exponent: Model transformation and numerical approximation

Meihui Zhang, Yaxue Liu, Mengmeng Liu +2

This work generalizes the subdiffusive Black-Scholes model by introducing the variable exponent in order to provide adequate descriptions for the option pricing, where the variable…
