We show that the field equations of Einstein–Gauss–Bonnet theory defined in generic $$D>4$$D>4 dimensions split into two parts one of which always remains higher dimensional, and hence the theory does not have a non-trivial limit to $$D=4$$D=4. Therefore, the recently introduced four-dimensional, novel, Einstein–Gauss–Bonnet theory does not admit an intrinsically four-dimensional definition, in terms of metric only, as such it does not exist in four dimensions. The solutions (the spacetime, the metric) always remain $$D>4$$D>4 dimensional. As there is no canonical choice of 4 spacetime dimensions out of D dimensions for generic metrics, the theory is not well defined in four dimensions.Publication Comment on “Einstein-Gauss-Bonnet Gravity in Four-Dimensional Spacetime”(American Physical Society (APS), 2020-09-28) Metin Gürses; Tahsin Çağrı Şişman; Bayram Tekin
