WEIGHTED HOMOGENEOUS MAP GERMS OF CORANK ONE FROM C ³ TO C ³ AND POLAR MULTIPLICITIES

Weighted Homogeneous Map Germs of Corank One from C3 to C3 and Polar Multiplicities

For quasi-homogeneous and finitely determined corank one map germs f : (C, 0) → (C, 0) we obtain formulae in function of the degree and weight of f for invariantes on the stable types of f , as polar multiplicities, number of Milnor, number of Lê. We minimize also the number of invariantes for 7, to resolve the problem that decides the Whitney equisingularity of families of such maps germs. To ...

3-Methyl­benzo[1,2-c:5,4-c′]dichromen-6(8H)-one

The title compound, C21H14O3, crystallizes with eight independent mol-ecules (A-H) in the asymmetric unit which are arranged in four groups of two mol-ecules each (AB, CD, EF and GH). In each mol-ecule, the pyran-2-one ring is planar (r.m.s. deviations vary from 0.001 to 0.017 Å), while the pyran ring has a screw-boat conformation. In the crystal, mol-ecules stack in two columns, along the [10-...

3 3 B c Results from CDF

CDF Run II detector has accumulated about 360 pb ¡ 1 data using dimuon triggers in p ¯ p collisions collected at ¢ s = 1.96 TeV. We report a first evidence for the B£ c meson in the fully reconstructed decay channel B c ¤ J¥ ψπ, and its mass measurement. In addition, we present ratio of branching fractions in B c ¤ J¥ ψ¦ modes, normalized to the B c ¤ J¥ ψK mode.

1-Acetyl-c-3,t-3-dimethyl-r-2,c-6-diphenyl­piperidin-4-one

In the title compound, C(19)H(21)NO, the piperidine ring adopts a chair conformation. The two phenyl rings attached to the piperidine ring at 2 and 6 positions occupy equatorial orientations and the dihedral angle between them is 57.53 (11)°. In the crystal, the mol-ecules are connected via weak inter-molecular C-H⋯π inter-actions, leading to a zigzag chains.
