Ten
sor renormalization group (TRG) is an algorithm introduced by Levin and Na
ve to implement a Migdal-Kadanoff-like iterative coarse-graining scheme fo
r lattice partition sums. It proved remarkably accurate for the 2D Ising m
odels and stimulated considerable further work to understand and improve t
he technical aspects of the algorithm leading to qualitative improvements
in the method.
\nIn this talk I will review (i) the early block spin
transformation idea and its TRG implementation\; (ii) analyticity constrai
nts on global phase diagrams\, including recent results in anisotropic lat
tices\; (iii) and explain the application of these results to realizing te
mporally ordered dynamic phases in quantum (discrete time) evolution with
measurements.
