The Nielsen number for nvalued multimaps, defined by Schirmer, has been calculated only for the circle. A concept of nvalued fiber map on the total space of a fibration is introduced. A formula for the Nielsen numbers of nvalued fiber maps of fibrations over the circle reduces the calculation to the computation of Nielsen numbers of singlevalued maps. If the fibration is orientable, the product formula for singlevalued fiber maps fails to generalize, but a “semiproduct formula ” is obtained. In this way, the class of nvalued multimaps for which the Nielsen number can be computed is substantially enlarged. Subject Classification 55M20, 54C60 1
On higher dimensional HirzebruchJung singularities
 Rev. Mat. Complut
"... A germ of normal complex analytical surface is called a HirzebruchJung singularity if it is analytically isomorphic to the germ at the 0dimensional orbit of an affine toric surface. Two such germs are known to be isomorphic if and only if the toric surfaces corresponding to them are equivariantly ..."

A germ of normal complex analytical surface is called a HirzebruchJung singularity if it is analytically isomorphic to the germ at the 0dimensional orbit of an affine toric surface. Two such germs are known to be isomorphic if and only if the toric surfaces corresponding to them are equivariantly isomorphic. We extend this result to higherdimensional HirzebruchJung singularities, which we define to be the germs analytically isomorphic to the germ at the 0dimensional orbit of an affine toric variety determined by a lattice and a simplicial cone of maximal dimension. We deduce a normalization algorithm for quasiordinary hypersurface singularities. 2000 Mathematics Subject Classification. Primary 32S10; Secondary 14M25. 1
