Functions on a Convex Set which are both omega-Semiconvex and omega-Semiconcave
omega, every function on G which is both semiconvex and semiconcave with modulus omega is (globally) C-1,C-omega-smooth. We show that this result is optimal Taylor theorem and (...

Smoothness via directional smoothness and Marchaud's theorem in Banach spaces
on [a, b], k is an element of N, and the (k + 1)th modulus of smoothness w(k+1) (f; t) is so small that eta(t) = integral(t)(0) omega(k+1)(f;s)/s(k+1) ds < +infinity for t with modulus C...

Gradient ranges of bumps on the plane
We show that the gradient range of a $C^1$-smooth function $b$ on the plane bounded support and the gradient $grad b$ admits a modulus of continuity $omega = omega (t)$ that satisfies $omega

Ranges of operators and derivatives
We show a unified method of proving the existence of C-1-Frechet smooth and Lipschitz mappings which are surjective or whose range of the derivative contains the whole dual unit ball. As an application, under Martin's Maxim...

Weak* dentability index of spaces C([0, alpha])
We compute the weak*-dentability index of the spaces C(K) where K is a countable compact space. Namely Dz(C([0,omega(omega alpha)]))=omega(1+alpha+1), whenever 0 <=alpha<omega(

First test of lepton flavor universality in the charmed baryon decays Omega(0)(c) -> Omega(-)l(+)nu(l) using data of the Belle experiment
We present the first observation of the Omega(0)(c) -> Omega(-)mu(+)nu(mu) decay and present measurements of the branching fraction ratios of the Omega(0)(c) -> Omega(-)l(+)nu(l) decays comp...

Observation of excited Omega(c) charmed baryons in e(+)e(-) collisions
Using the entire Belle data sample of 980 fb(-1) of e(+)e(-) collisions, we present the results of a study of excited Omega(c) charmed baryons in the decay mode (sic)(c)(+) K-. We show confirmation of four of the f...
