Are there classes for that FO-model checking is FPT on hypergraphs?
For graphs, there are many classes that admit FPT-algorithms for model checking of first order logic, e.g. the class of nowhere dense graphs by Grohe et. al.
Are there similar results for ($k$-uniform)...

Follow-up on Nair/Tetali's Correlation Decay Tree for hypergraphs?
I'm wondering if anybody has followed up on Nair/Tetali's correlation decay tree construction for hypergraphs. I didn't find anything relevant in back-citation on google scholar. Interesting question ...

What kind of solver should I use for this hypergraph problem?
I have to list the solutions to the following hypergraph problem:
There is a set of nodes, linked by edges that are 2-to-1 and bidirectional. The possible directions are either direct: 2 sources and 1 ...

Tractability of computing generalized hypertreewidth on bounded arity hypergraphs
Generalized hypertreewidth is a generalization of treewidth to hypergraphs. Unlike treewidth, it is not tractable, for a fixed width $k \in \mathbb{N}$, given a hypergraph $H$, to determine if $H$ has ...

Hardness of vertex colouring on hypergraphs with $O(\log n)$ edges
I'm interested to know whether there has been any work done on the problem in the title. For the problem to be meaningful, we would naturally need that the hyperedges must have large ($\omega(1)$) ...

Detecting bridges in Hypergraph S-t Reachability
Is there a fast algorithm to detect possible bridge arcs in hyperpaths from set $S$ of nodes to node $t$ in a hypergraph $G$. That is, given a hypergraph $G$, source nodes $S$, and target node $t$, ...
