Investigation of COVID-19 mathematical model under fractional order derivative

The given article is devoted to presentation of some results regarding existence and uniqueness solution a fractional order model that addressing the effect immigration on transmission dynamics population model. Further, in view this investigation have been checked recent pandemic known as Corona virus COVID-19. concerned established by using fixed point theory approach. After qualitative analysis considered model, applying Laplace transform along with decomposition method, we calculated series type for unknown quantities each equation decomposed into small calculate quantity very easily adding first few terms said quantities. Approximate testing data different cases are illustrate results.
