Seminar Spatiotemporal cat map blog (nov 2021) Working notes -very rough, read at your own risk, with many literature pointers- on our elegant, analytically soluble baby model of a spatiotemporally discretized chaotic field theory, on the Ising model / Ihara zeta functions literature of potential relevance to the spatiotemporal reformulation of turbulent field theories. There are many promising directions to ponder here.

Chapter - Spatiotemporal theory of turbulence

Seminar Spatiotemporal blog (dec 2017)
Working notes -very rough, read at your own risk, but with lots of literature pointers- on how to recast finding invariant solutions of the 1D Kuramoto-Sivashinsky PDE into the problem of finding spatio-temporal fixed point solutions. The point is that we have give up on finding invariant solutions by forward integration in time from specified intial conditions - instead, we have to develop variational methods to multiply-periodic solutions in spacetime. In particular, it would be very nice if someone writes a working spatiotemporal solver and runs it on some higly parallelized machine.
