Two remarks on the Suita conjecture

Nikolai Nikolov (2015)

Annales Polonici Mathematici

It is shown that the weak multidimensional Suita conjecture fails for any bounded non-pseudoconvex domain with C 1 + ε -smooth boundary. On the other hand, it is proved that the weak converse to the Suita conjecture holds for any finitely connected planar domain.

Une remarque sur l'hyperbolicité injective

Jean-Pierre Vigué (1989)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

In this Note, I prove that, in many cases, the injective Kobayashi pseudodistance, as defined by Hahn, is equal to the Kobayashi pseudodistance.

Uniform estimates for the Cauchy-Riemann equation on q -convex wedges

Christine Laurent-Thiébaut, Jurgen Leiterer (1993)

Annales de l'institut Fourier

We study the -equation with Hölder estimates in q -convex wedges of n by means of integral formulas. If D n is defined by some inequalities { ρ i 0 } , where the real hypersurfaces { ρ i = 0 } are transversal and any nonzero linear combination with nonnegative coefficients of the Levi form of the ρ i ’s have at least ( q + 1 ) positive eigenvalues, we solve the equation f = g for each continuous ( n , r ) -closed form g in D , n - q r n , with the following estimates: if d denotes the distance to the boundary of D and if d β g is bounded, then for all ϵ > 0 ,...

Weak lineal convexity

Christer O. Kiselman (2015)

Banach Center Publications

A bounded open set with boundary of class C¹ which is locally weakly lineally convex is weakly lineally convex, but, as shown by Yuriĭ Zelinskiĭ, this is not true for unbounded domains. The purpose here is to construct explicit examples, Hartogs domains, showing this. Their boundary can have regularity C 1 , 1 or C . Obstructions to constructing smoothly bounded domains with certain homogeneity properties will be discussed.
