| Research Abstract |
Although the theory of multiplicity of local rings is very important as a classical theory in commutative algebra, but it can be applied to only ideals containing some power of the maximal ideal. Hence a generalized invariant named "j-multiplicity" was introduced. However, it was really difficult to compute its value. In this research, we established a practical method for computing the j-multiplicity of a given ideal.
