Abstract
We use the concept of dual Goldie dimension and a characterization of semi-local rings due to Camps and Dicks (1993) to find some classes of modules with semi-local endomorphism ring. We deduce that Linearly co mpact modules have semi-local endomorphism ring, cancel from direct su ms and satisfy the n th root uniqueness property. We also deduce that modules over commutative rings satisfying AB5 also cancel from direct sums and satisfy the n th root uniqueness property.
