Abstract New selenophenes were prepared from ketene dithioacetals. Isoselenocyanates were used to acceded to aminoselenophenes. Starting from substituted methylsulfanylselenophenes thieno- and selenolo-selenophenes were synthetized. 相似文献

In this paper, using the ring structure of the space of circulant (2 × 2)-matrix, we characterize the dual of the (Fréchet)
space of germs of left Hermitean monogenic matrix functions in a compact set
_boxclose_boxclose_boxclose_boxclose_boxclose_boxclose_boxclose_boxclose R^2n{{\bf E}\subset\mathbb R^{2n}}. As an application we describe the dual space of the so-called h-monogenic functions satisfying simultaneously two Dirac type equations. 相似文献

In this paper, we define a q-deformation of the Dirac operator as a generalization of the one dimensional q-derivative. This is done in the abstract setting of radial algebra. This leads to a q-Dirac operator in Clifford analysis. The q-integration on
\mathbbRm{\mathbb{R}^m}, for which the q-Dirac operator satisfies Stokes’ formula, is defined. The orthogonal q-Clifford- Hermite polynomials for this integration are briefly studied. 相似文献

In the even dimensional case the discrete Dirac equation may be reduced to the so-called discrete isotonic Dirac system in
which suitable Dirac operators appear from both sides in half the dimension. This is an appropriated framework for the development
of a discrete Martinelli–Bochner formula for discrete holomorphic functions on the simplest of all graphs, the rectangular
\mathbbZm{\mathbb{Z}^m} one. Two lower-dimensional cases are considered explicitly to illustrate the closed analogy with the theory of continuous
variables and the developed discrete scheme. 相似文献

The reactions of isoselenocyanates with carbodiimides in refluxing hexane afforded 1,3‐selenazetidine‐2,4‐diimines 3a – 3h by a [2+2] cycloaddition in moderate‐to‐good yields. The molecular structure of 3a has been established by X‐ray crystallography. 相似文献

In this paper we generalize the concept of primitivation of monogenic functions taking values in a Clifford algebra, which
is on its own a generalization to higher dimension of the primitivation problem for holomorphic functions in the complex plane.
This problem can be stated as follows: given a monogenic function
on
, i.e. a solution for the generalized Cauchy-Riemann operator D on
, construct a monogenic function
such that
. In view of the fact that, for monogenic functions g, this can be written as
g = f, a straightforward generalization consists in replacing the scalar generator
of translations in the x
0-direction by a generator of another transformation group. In this paper we consider translations in more dimensions. 相似文献

The space HF
k
(Ω) of harmonic multi-vector fields in a domain
as introduced in [1] is closely connected to the space of harmonic forms. The main aim of this paper is to characterize the
dual space of HF
k
(E) being
a compact set. It is proved that HF
k
(E)* is isomorphic to a certain quotient space of so-called harmonic pairs outside E vanishing at infinity.
