Abstract
In 1996 Rainer Brück considered the uniqueness problem of an entire function that shares one value with its derivative. He proposed a conjecture on the single value sharing by an entire function with its first derivative[14]. Till date the conjecture of Brück is not completely resolved in its full generality. However it initiated a stream of research on a new branch of uniqueness theory. In the survey we intend to present the development of works done by several authors on the conjecture.
