“…More recently in (Khalil et al, 2014), the first conformable calculus was introduced that is an alternative to conformal calculus, but with local operators, without memory. These conformable operators can improve the performance of conformal operators for example (see Meléndez-Vázquez et al, 2021;Reyes-Luis et al, 2021;Meléndez-Vázquez et al, 2020), since these operators can introduce a function that conformal operators cannot, regardless of the non-integer order of these derivatives.…”
