Conjecture on infinite-dimensional random attractors under infinite energy mean
Conjecture on infinite-dimensional random attractors under infinite energy mean
Let , , and satisfy
and let be a nonlinearity and a right-hand side satisfying the assumptions of Theorem 5. Let
\mathcal A($\eta) be the associated random attractor in the energy space $E$. **Infinite-dimensional attractor conjecture.** There are a nonlinearity $f$ and \right-hand side $g$ satisfying those assumptions such thatmathcal A(E$.
The parameter condition makes the constructed energy bound have infinite mean. The conjecture proposes that this lack of a first energy moment can lead to attractors with infinite Hausdorff and fractal dimensions; the source gives no resolution.
