For functions (fϵ​)ϵ∈{0,1}3​ on Fpn​, the Gowers inner product is
⟨(fϵ​)⟩U3​=Ex,h1​,h2​,h3​​∏ϵ∈{0,1}3​C∣ϵ∣fϵ​(x+ϵ1​h1​+ϵ2​h2​+ϵ3​h3​),
(1)
where C is the complex conjugate operator. The Gowers uniformity norm is
∥f∥U3​=⟨(f)ϵ∈{0,1}3​⟩U31/8​.
(2)
The Gowers-Cauchy-Schwarz inequality states
∣⟨(fϵ​)⟩U3​∣≤∏ϵ∈{0,1}3​∥fϵ​∥U3​.

Solved by gpt-5.6-sol high.
