Ideal quotient
BINARY OPERATION DEFINED ON THE SET OF IDEALS IN A COMMUTATIVE RING; (I:J) CONSISTS OF ELEMENTS R OF THE COMMUTATIVE RING SUCH THAT RJ IS A SUBSET OF I; IN ALGEBRAIC GEOMETRY, CORRESPONDS TO THE SET DIFFERENCE OF SUBVARIETIES
Quotient ideal; Colon ideal
In abstract algebra, if I and J are ideals of a commutative ring R, their ideal quotient (I : J) is the set
