PY - 2022 TI - To investigate a class of multi-singular pointwise defined fractional q–integro-differential equation with applications JO - AIMS Mathematics SP - 7781 EP - 7816 VL - 7 IS - 5 AB - In the research work, we discuss a multi-singular pointwise defined fractional q–integro-differential equation under some boundary conditions via the Riemann-Liouville q–integral and Caputo fractional q–derivatives. New existence results rely on the α-admissible map and fixed point theorem for α- ψ -contraction map. At the end, we present an example with application and some algorithms to illustrate the primary effects. UR - https://doi.org/10.3934/math.2022437 DO - 10.3934/math.2022437
