Abstract

I will show first that on an algebraic curve (singular) a MJ-multiplier ideal is essentially the same as an integrally closed ideal. Secondly, I will show that on a curve (singular) by comparing MJ-multiplier ideal with the conductor ideal, we can deduce a criterion when the curve is locally a complete intersection.
