Extend sparse hypergraph enumeration asymptotics to larger maximum degrees

Determine whether the asymptotic enumeration formula of Aldesari and Greenhill for t-uniform hypergraphs with a prescribed degree sequence and forbidden edges extends to degree sequences whose maximum degree is o(n^{(t-1)/t}).

Background

The paper compares its sparse hypergraphicality results with an enumeration formula of Aldesari and Greenhill. That formula applies when the maximum degree d and total degree sum Sigma satisfy t4 d3=o(Sigma), a condition that requires d=o(n{1/2}) in the relevant setting. The authors explicitly ask whether the enumeration result can be extended to the substantially broader maximum-degree range o(n{(t-1)/t}).

References

A natural open question if the results of Aldesari and Greenhill can be extended to degree sequences with maximum degree $o(n{\frac{t-1}{t})$.
