Module theory

Torsionless module

In abstract algebra, a module M over a ring R is called torsionless if it can be embedded into some direct product RI. Equivalently, M is torsionless if each non-zero element of M has non-zero image under some R-linear functional f: This notion was introduced by Hyman Bass. (Wikipedia).

Commutative algebra 45: Torsion free modules

This lecture is part of an online course on commutative algebra, following the book "Commutative algebra with a view toward algebraic geometry" by David Eisenbud. We finish the survey of types of modules by briefly discussing torsion-free and coprimary modules. We show that flat modules a
