FO Model Checking of Interval Graphs

We study the computational complexity of the FO model checking problem on interval graphs, i.e., intersection graphs of intervals on the real line.The main positive result is that FO model checking and successor-invariant FO model ut solution gel for cats checking can be solved in time O(n log n) for n-vertex interval graphs with representations co
