We prove the "End Curve Theorem," which states that a normal surface singularity .X;o/ with rational homology sphere link 6 is a splice quotient singularity if and only if it has an end curve function for each leaf of a good resolution tree. An "end curve function" is an analytic function .X;o/! .C; 0/ whose zero set intersects 6 in the knot given by a meridian curve of the exceptional curve corresponding to the given leaf. A "splice quotient singularity".X;o/ is described by giving an explicit set of equations describ- ing its universal abelian cover as a complete intersection in C t , wheret is the number of leaves in the resolution graph for.X;o/, together with an explicit description of the covering transformation group. Among the immediate consequences of the End Curve Theorem are the previously known results: .X;o/ is a splice quotient if it is weighted homogeneous (Neumann 1981), or rational or minimally elliptic (Okuma 2005).
