Depth reduction of a class of Witten zeta functions
David M. Bradley, Tianxin Cai, Xia Zhou
We show that if a,b,c,d,f are positive integers such that a+b+c+d+f is even, then the Witten zeta value zeta_{sl(4)}(a,b,c,d,0,f) is expressible in terms of Witten zeta functions w…

On Mordell-Tornheim sums and multiple zeta values
David M. Bradley, Xia Zhou
We prove that any Mordell-Tornheim sum with positive integer arguments can be expressed as a rational linear combination of multiple zeta values of the same weight and depth. By a…

An infinite series for the natural logarithm that converges throughout its domain and makes concavity transparent
David M. Bradley
The natural logarithm can be represented by an infinite series that converges for all positive real values of the variable, and which makes concavity patently obvious. Concavity of…
