报告摘要：A hypergraph is linear if each pair of distinct vertices appears in at most one common edge. We say G=(V,E) is an associated graph of a linear hypergraph H=(V, X) if for any x in X, the induced subgraph G[x] is a cycle, and for any e in E, there exists a unique edge y in X such that e is a subset of y. A linear hypermap M is a 2-cell embedding of a connected linear hypergraph H's associated graph G on a compact connected closed surface, such that for any edge x in E(H), G[x] is the boundary of a 2-cell. In this talk, we introduce the monodromy groups of linear hypermaps.
