Averaging operators over homogeneous varieties over finite fields

Doowon Koh, Chun-Yen Shen, Igor Shparlinski

In this paper we study the mapping properties of the averaging operator over a variety given by a system of homogeneous equations over a finite field. We obtain optimal results on…

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 $A = (a_{j, k})_{j, k \geq 1}$ be a non-negative matrix. In this paper, we characterize those $A$ for which $∥ A ∥_{ℓ_{p}, ℓ_{q}}$ 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 $A = (a_{j, k})_{j, k \geq 1}$ be a non-negative matrix. In this paper, we characterize those $A$ for which $∥ A ∥_{E, F}$ are determined by their actions on decreasing sequences, w…
