GEOMETRY OF MODULUS SPACES
"... Abstract. Let φ be a modulus function, i.e., continuous strictly increasing function on [0, ∞), such that φ(0) = 0, φ(1) = 1, and φ(x + y) ≤ φ(x) + φ(y) for all x, y in [0, ∞). It is the object of this paper to characterize, for any Banach space X, extreme points, exposed points, and smooth point ..."

Modulus and the Poincaré inequality on metric measure spaces
- Mathematische Zeitschrift
"... Abstract. We show that, in a complete metric measure space equipped with a doubling Borel regular measure, the Poincare ́ inequality with upper gradients in-troduced by Heinonen and Koskela [HK98] is equivalent to the Poincare ́ inequality with “approximate Lipschitz constants ” used by Semmes in [S ..."

Discrete Modulus of Smoothness of Splines with Equally Spaced Knots
, 1995
"... . We study the behavior of moduli of smoothness of splines s of order r with equally spaced knots fx i g, x i+1 \Gamma x i = h. The main results are (1) For each 0 m ! r, all quantities h j !m\Gammaj (s (j) ; h)p , 0 j m, are equivalent and can be measured by a discrete norm of the mth differ ..."

, in the results above, all the quantities can still be measured by the corresponding discrete modulus multiplied by a power of t=h. The results generalize the notion of discrete norm of B-spline series in case of equal spacing. As an application, we use these results to prove that ! 3 is the best rate of convex
An Analysis of Constant Modulus Receivers
