Tight closure

In mathematics, in the area of commutative algebra, tight closure is an operation defined on ideals in positive characteristic. It was introduced by Melvin Hochster and Craig Huneke (1988, 1990). Let R be a commutative noetherian ring containing a field of characteristic p > 0 . Hence p is a prime number. Let I be an ideal of R . The tight closure of I , denoted by I ∗ , is another ideal of R containing I . The ideal I ∗ is defined as follows. Here I [ p e ] is used to denote the ideal of R gene
