Evaluations of some series via the WZ method

Qing-Hu Hou, Zhi-Wei Sun

In this paper, we evaluate some series via the WZ method, and confirm several previous conjectures. For example, we prove the following two identities conjectured by the second aut…

Determination of the two-color Rado number for $a_{1} x_{1} + ... + a_{m} x_{m} = x_{0}$

Song Guo, Zhi-Wei Sun

For positive integers $a_{1}, a_{2}, ..., a_{m}$ , we determine the least positive integer $R (a_{1}, ..., a_{m})$ such that for every 2-coloring of the set $[1, n] = 1, ..., n$ with $n\ge R(a_1,...,a…
