A locally finite model for gravity
Gerard 't Hooft
Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet d…

Invariance under complex transformations, and its relevance to the cosmological constant problem
Gerard 't Hooft, Stefan Nobbenhuis
In this paper we study a new symmetry argument that results in a vacuum state with strictly vanishing vacuum energy. This argument exploits the well-known feature that de Sitter an…
