Conjecture on connected simple systems of parameterized Conley indices

Let ZZ be a Hausdorff space, let ω ⁣:MZ\omega\colon M\to Z be continuous, and let P=(P1,P2)P=(P_1,P_2) range over regular index pairs for an isolated invariant set SS. The parameterized Conley index is the ex-space (Iω(P),rP,sP)(I_\omega(P),r_P,s_P), where

Iω(P)=(Z×0)(P1×1)/,I_\omega(P)=(Z\times 0)\cup(P_1\times 1)\mathbin{/}\sim,

with (x,1)(ω(x),0)(x,1)\sim(\omega(x),0) for xP2x\in P_2, and with the canonical section and projection sPs_P and rPr_P. Parameterized Conley-index conjecture. The parameterized Conley indices (Iω(P),rP,sP)(I_\omega(P),r_P,s_P), as PP ranges over all regular index pairs for SS, form a connected simple system. The corresponding assertion for unparameterized Conley indices is stated as a theorem in the source; the parameterized analogue is proposed as a conjecture.
