A note on the possible existence of an instanton-like self-dual solution to lattice Euclidean gravity
The Journal of High Energy Physics, 2017, 2017(2): 044.
The self-dual solution to lattice Euclidean gravity is constructed. In contrast to the well known Eguchi-Hanson solution to continuous Euclidean Gravity, the lattice solution is asymptotically globally Euclidean, i.e., the boundary of the space as r -> infinity is S-3=SU(2).
