We study pseudo Yang-Mills fields on a compact strictly pseudoconvex CR manifold M , i.e. the critical points of the functional PYM(D) = 1 2 ∫ M ‖πHR‖θ∧(dθ), where D is a connection in a Hermitian CR-holomorphic vector bundle (E, h) → M . Let Ω = {φ < 0} ⊂ C be a smoothly bounded strictly pseuodoconvex domain and g the Bergman metric on Ω. We show that boundary valuesDb of Yang-Mills fieldsD on...

We show that any contact form whose Fefferman metric admits a nonzero parallel vector field is pseudo-Einstein of constant pseudohermitian scalar curvature. As an application we compute the curvature groups H(C(M),Γ) of the Fefferman space C(M) of a strictly pseudoconvex real hypersurface M ⊂ C. 1. Statement of results Let M be a strictly pseudoconvex CR manifold of CR dimension n and θ a conta...

For a general logic program, a set of n+ 1 logic values is considered and an unde ned value denoted u. Partial multi-valued interpretations are also de ned. A general logic program P may contain the constants that are de ned for every logic value. A pseudo-negation denoted eh is de ned for every integer h, where 0 h < n. A partial ordering denoted h is de ned between multi-valued interpretation...

Multi-verb constructions are an areal feature of Kalahari Basin Area languages (“Khoisan”), a Sprachbund comprising the Kx’a, Tuu, and Khoe-Kwadi families. Presently, these characterised by two distinct multi-verb with specific distributions: strictly contiguous serial verb in Kx’a Tuu correspond to involving morphophonological linker, or “juncture”, Khoe-Kwadi. This paper describes additional ...

We wish to draw attention to an interesting and promising interaction of two theories. On the one hand, it is the theory of pseudo-triangulations which was useful for implicit solution of the carpenter’s rule problem and proved later to give a nice tool for graph embeddings. On the other hand, it is the theory of hyperbolic virtual polytopes which arose from an old uniqueness conjecture for con...

Let Ω be a bounded C∞-smoothly bounded domain in C. For such a domain we define a new notion between strict pseudo-convexity and pseudo-convexity: the size of the set W of weakly pseudo-convex points on ∂Ω is small with respect to Minkowski dimension: near each point in the boundary ∂Ω, there is at least one complex tangent direction in which the slices of W has a upper Minkowski dimension stri...

In this paper, we introduce a modified Mann iterative process for strictly pseudo-contractive mappings and obtain a strong convergence theorem in the framework of q-uniformly smooth Banach spaces. Our results improve and extend the recent ones announced by (Kim and Xu 2005), (Xu 2004) and some others.
