This question is about Page 125 of the book "Cellular automata in hyperbolic spaces: Volume 2" By Maurice Margenstern, Publisher Archives contemporaines, 2008.
In the author's opinion, the question P=NP is ill-posed because in the hyperbolic setting P=NP or in the notation used later in the book Ph=NPh.
I don't know enough about complexity to know what to make of this, but it sounds interesting.
So the question is basically, what do you make of it?
Do his claims make sense ?
