TY - GEN A1 - Beckenbach, Isabel A1 - Scheidweiler, Robert T1 - Perfect f-Matchings and f-Factors in Hypergraphs - A Combinatorial Approach N2 - We prove characterizations of the existence of perfect f-matchings in uniform mengerian and perfect hypergraphs. Moreover, we investigate the f-factor problem in balanced hypergraphs. For uniform balanced hypergraphs we prove two existence theorems with purely combinatorial arguments, whereas for non-uniform balanced hypergraphs we show that the f-factor problem is NP-hard.
