有限域上的二次Fourier分析是加法組合的一個(gè)重要方面,其內(nèi)容主要涉及關(guān)于‖·‖U3(三次Gowers范數(shù))的逆定理與Koopman-von Neumann分解(3-Kv N),研究與‖·‖Ud相應(yīng)的d-Kv N成為一個(gè)自然的問(wèn)題.本研究給出了d-Kv N的一種形式.

Quadratic Fourier analysis in finite field is one important part of the additive combinatorics.It mainly contains inverse theorem for the GowersU3-norm and Koopman-von Neumann decomposition(3-Kv N).d-Kv N relevant to the GowersU d-norm is a very natural problem,and a form ofd-Kv N is introduced in the paper.
