3-Chloro-N′-(4-hydroxybenzylidene)benzohydrazide
The title compound, C14H11ClN2O2, was prepared by the reaction of 4-hydroxybenzaldehyde with 3-chlorobenzohydrazide in methanol. The dihedral angle between the two benzene rings is 38.2 (2)°. In the crystal, molecules are linked through intermolecular N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds, forming layers lying parallel to the bc plane
Vector and Spinor Decomposition of SU(2) Gauge Potential, their quivalence and Knot Structure in SU(2) Chern-Simons Theory
In this paper, spinor and vector decomposition of SU(2) gauge potential are
presented and their equivalence is constructed using a simply proposal. We also
obtain the action of Faddeev nonlinear O(3) sigma model from the SU(2) massive
gauge field theory which is proposed according to the gauge invariant
principle. At last, the knot structure in SU(2) Chern-Simons filed theory is
discussed in terms of the --mapping topological current theory. The
topological charge of the knot is characterized by the Hopf indices and the
Brouwer degrees of -mapping.Comment: 10 pages, ni figur
