The universal bifurcation diagram conjecture

Let R:XXR:X\to X be the renormalization operator from the theorem of Multiverse chaos. A bifurcation diagram is the diagram recording the bifurcations occurring along a homotopy of dynamical systems.

Universal bifurcation diagram conjecture. There exists a homotopy

Rt:XX,t[0,1],R_t:X\to X,\qquad t\in[0,1],

such that R1=RR_1=R, while R0R_0 has simple dynamics, for example a finite number of periodic orbits. In particular, the bifurcation diagram R\frak{R} of this curve is well-defined. Moreover, if gt:SSg_t:S\to S, t[0,1]t\in[0,1], is a C1C^1-isotopy of a closed, smooth manifold SS of dimension d>1d>1, and Γg\Gamma_g denotes the bifurcation diagram of gtg_t, then Γg\Gamma_g can be embedded as a subgraph of R\frak{R}.

This conjecture proposes a universal bifurcation analogue of the theorem of Multiverse chaos: a single renormalization homotopy should contain, as subgraphs, the bifurcation diagrams of all such isotopies.
