Complex symplectic structures and the partial derivative partial derivative-lemma

2018
In this paper, we study complex symplectic manifolds, i.e., compact complex manifolds X which admit a holomorphic (2, 0)-form σ which is d-closed and non-degenerate, and in particular the Beauville–Bogomolov–Fujiki quadric Q_σ associated with them. We will show that if X satisfies the ∂∂ ̄ -lemma, then Q_σ is smooth if and only if h^(2,0)(X)=1 and is ...

Probabilistic representation of fundamental solutions to partial derivative u/partial derivative t = K-m partial derivative(m)u/partial derivative x(m)

2012
For the fundamental solutions of heat-type equations of order n we give a general stochastic representation in terms of damped oscillations with generalized gamma distributed parameters. By composing the pseudo-process X-m related to the higher-order heat-type equation with positively skewed stable r.v.'s T-1/3(j), j = 1, 2, . . . , n we obtain genuine

Partial derivatives of Bézier surfaces

Computer-Aided Design, 1996
In order to apply differential geometry to surfaces defined by splines, it is imperative to have an algorithm that yields the partial derivatives of the coordinates functions of the surface. The author shows that in the same way as Horner's scheme for the computation of function values can be modified to yield the derivatives with little extra ...

Partially Chlorinated Derivatives of Rubber

Rubber Chemistry and Technology, 1949
Abstract Chlorinated rubbers containing from 1 to 17 per cent of chlorine were prepared by direct chlorination, at ordinary temperature, of crepe rubber dissolved in carbon tetrachloride. These products retain, to a greater or lesser degree, rubberlike properties, and are capable of hot or cold vulcanization with or without the addition of ...
