Abstract: The point of this talk is introduce the notion of tight closure in commutative algebra. First defined and studied by Mel Hochster and Craig Huneke in the late 1980's, the notion of tight closure had developed into a vital tool in the study of commutative algebra and algebraic geometry. We will discuss the basic concepts, key theorems, and the history of tight closure
