If you have a question about this talk, please contact Dr Andrew Treglown. Given an hypergraph F, a perfect F-tiling in a hypergraph H is a spanning collection of disjoint copies of F. A related notion is that of an F-covering, where we cover every vertex of the host graph H with copies of F, but we no longer insist that the copies are disjoint. The problem of determining the least value of the minimum degree in a graph that ensures the existence of a perfect F-tiling (or F-covering) is well understood in the case of graphs. The situation is different for general uniform hypergraphs, where determining these thresholds is an active field of research. In this talk I will review some of the known results for hypergraphs and present some new results in the case where F is a tight cycle, which is a natural generalization of cycles for uniform hypergraphs. Joint work with Jie Han and Allan Lo. This talk is part of the Combinatorics and Probability Seminar series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
