We study monomial flocks of quadratic cones of PG(3, q), with emphasis on the case where the flock is semifield, providing some nonexistence and some uniqueness results. In addition, we give a computer-free proof of the existence of the sporadic semifield flock of the quadratic cone of PG(3, 35) (and hence of the sporadic translation ovoid of Q(4, 35)), and relate that flock to the sporadic simple group M11.
The equivalence between saddle-points and optima, and duality theorems are established for a much larger class of non-smooth non-convex problems in which functions are locally Lipschitz and are satisfying invex-type conditions of Hanson and Craven.
A special Hopf bifurcation in resistive magnetohydrodynamics can easily be identified by starting from a particularly suitable form of the linearized equations which was previously introduced by the author. As usual, the bifurcation can lead to nonlinear periodic oscillations. These oscillations can eventually be destroyed, which raises the question of the nature of the ultimate Cheap Ghd Sale Co Uk
We experimentally study the behaviour of a parametrically driven damped pendulum in a parameter region where a transient chaotic motion is observed. We reconstruct the chaotic saddle and a chaotic attractor near an Cheap Babyliss Pro Curl
interior crisis in a stroboscopic phase representation and give an estimation of the corresponding f(α) spectra.
