In this work, we present a computational method for solving eigenvalue problems of fourth-order ordinary differential equations which based on the use of Chebyc
In this paper, we consider a leptospirosis epidemic model to implement optimal campaign by using multiple control variables. First, we show the existence of the
In this paper, we consider the giving up smoking model. First, we present the giving up smoking model in fractional order. Then the homotopy analysis method (HA
