Abstract
In this paper, we investigate Mobius groups theory in the framework of bicomplex numbers, which are pairs of complex numbers making up a commutative ring with zero-divisors. We shall generalize classical Jorgensen' inequality to bicomplex analysis and obtain an analogue of Jorgensen type inequality for discrete non-elementary Mobius groups of bicomplex setting generated by two elements.
