Abstract
Over , Henry Laufer classified all taut surface singularities. We adapt and extent his transcendental methods to positive characteristic. With this we show that if a normal surface singularity is taut over , then the normal surface singularities with isomorphic dual graph over algebraically closed fields of characteristic exponent are taut for all but finitely many . We conjecture that this is actually "if and only if".
