有限域上的二次Fourier分析是加法组合的一个重要方面,其内容主要涉及关于‖·‖U3(三次Gowers范数)的逆定理与Koopman-von Neumann分解(3-Kv N),研究与‖·‖Ud相应的d-Kv N成为一个自然的问题.本研究给出了d-Kv N的一种形式.

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.
