Infinite-order monodromy conjecture for positive-geometric-genus surface singularities
Infinite-order monodromy conjecture for positive-geometric-genus surface singularities
Let be a -dimensional weighted-homogeneous isolated hypersurface singularity with rational homology -sphere link , Milnor fiber , and monodromy of its Milnor fibration. The geometric genus of is denoted by . Infinite-order monodromy conjecture. The answer to whether has infinite order in the smooth mapping class group is affirmative when . The claim extends the known affirmative result for and contrasts with the negative answer for ADE singularities, which have ; the general case remains open.
