Positivity analysis for mixed order sequential fractional difference operators

PO Mohammed, D Baleanu, T Abdeljawad, SK Sahoo…

We consider the positivity of the discrete sequential fractional operators(RL a0+ 1∇ ν1 RL a0∇ ν2 f)(τ) defined on the set 31 (see (1.1) and Figure 1) and(RL a0+ 2∇ ν1 RL a0∇ ν2 f)(τ) of mixed order defined on the set 32 (see (1.2) and Figure 2) for τ∈ …
