On C$^2$-smooth Surfaces of Constant Width
Tbilisi Mathematical Journal, 2007 A number of results for C$^2$-smooth surfaces of constant width in Euclidean 3-space ${\mathbb{E}}^3$ are obtained. In particular, an integral inequality for constant width surfaces is established. This is used to prove that the ratio of volume to cubed width of a constant width surface is reduced by shrinking it along its normal lines.

On the nonuniform Berry--Esseen bound [PDF]
, 2013 Due to the effort of a number of authors, the value c_u of the absolute constant factor in the uniform Berry--Esseen (BE) bound for sums of independent random variables has been gradually reduced to 0.4748 in the iid case and 0.5600 in the general case ...

The Dunkl–Williams constant, convexity, smoothness and normal structure
Journal of Mathematical Analysis and Applications, 2008 In 1964, \textit{C. F. Dunkl} and \textit{K. S. Williams} [Am. Math. Monthly 71, No. 1, 53--54 (1964; Zbl 0178.16202)] proved that \[ \left\| \frac{x}{\| x \|} - \frac{y}{\| y \|} \right\| \leq \frac{4}{\| x \| + \| y \| } \| x - y \| \] for nonzero elements \(x\) and \(y\) in a normed linear space \(X\) and noted that the constant \(4\) in the ...
