Fourier analysis and expanding phenomena in finite fields
Derrick Hart, Liangpan Li, Chun-Yen Shen
In this paper the authors study set expansion in finite fields. Fourier analytic proofs are given for several results recently obtained by Solymosi, Vinh and Vu using spectral grap…
Characterization of the matrix whose norm is determined by its action on decreasing sequences:The exceptional cases
Chang-Pao Chen, Chun-Yen Shen, Kuo-Zhong Wang
Let be a non-negative matrix. In this paper, we characterize those for which are determined by their actions on non-negative d…
Characterization of the matrix whose norm is determined by its action on decreasing sequences
Chang-Pao Chen, Hao-Wei Huang, Chun-Yen Shen
Let be a non-negative matrix. In this paper, we characterize those for which are determined by their actions on decreasing sequences, w…
Garaev's Inequality in finite fields not of prime order
Nets Hawk Katz, Chun-Yen Shen
We prove a version of Garaev's sum product theorem in the set of finite fields with non-prime order. Because of the presence of subfields, this seems to require some hypotheses on…
A Slight Improvement to Garaev's Sum Product Estimate
Nets Hawk Katz, Chun-Yen Shen
We slightly improve Garaev's recent sum-product estimate largely by using Plunneke's inequality a little more efficiently. We improve the exponent from 15/14 to 14/13.
