Topology of the blow up set for the Seiberg-Witten monopoles with multiple spinors Andriy Haydys Universität Bielefeld A sequence of the Seiberg-Witten monopoles with multiple spinors on a three-manifold can converge after a suitable rescaling to a Fueter section, say I, only on the complement of a subset Z. I will discuss the following question: Which pairs (I,Z) can (or can not) appear as the limit of a sequence of the Seiberg-Witten monopoles?
