%0 Journal Article %T Arithmetic harmonic analysis for smooth quartic Weyl sums: three additive equations %A Joerg Bruedern %A Trevor D. Wooley %J Mathematics %D 2015 %I arXiv %X We establish the non-singular Hasse principle for systems of three diagonal quartic equations in 32 or more variables, subject to a certain rank condition. Our methods employ the arithmetic harmonic analysis of smooth quartic Weyl sums and also a new estimate for their tenth moment. %U http://arxiv.org/abs/1507.07465v1
