The pseudorandomness conjecture for nondegenerate linear maps

About 7 years old · traced to

Let m,dm,d be natural numbers with d⩾m+2d\geqslant m+2, and let L:Rd→RmL:\mathbb{R}^d\to\mathbb{R}^m be a surjective linear map. Let Vdegen⁡∗(m,d)V^*_{\operatorname{degen}}(m,d) denote the degenerate locus, and let νN,wγ\nu_{N,w}^{\gamma} be the pseudorandom majorant defined from the smooth sieve weight. Pseudorandomness conjecture. If L∉Vdegen⁡∗(m,d)L\notin V^*_{\operatorname{degen}}(m,d), then there exist a value of γ\gamma and a function w:N→R⩾0w:\mathbb{N}\to\mathbb{R}_{\geqslant 0} with w(N)→∞w(N)\to\infty as N→∞N\to\infty such that νN,wγ\nu_{N,w}^{\gamma} is (L,w)(L,w)-pseudorandom. This would extend the proved pseudorandomness theorem from algebraic-coefficient maps to all nondegenerate surjective linear maps.
