The remaining two-variable question
Statement
For P,Q ∈ ℂ[x₁,x₂] and independent standard real Gaussians X₁,X₂, does E[P(X)^m] = 0 for every positive integer m imply E[Q(X)P(X)^m] = 0 for all sufficiently large m?
Assumptions
- Exactly two real Gaussian coordinates.
- Complex coefficients and a Q-dependent threshold.
Scope
This restriction is unresolved in Long’s dimension discussion.
