It is proved that positive solutions concentrate on a point in the domain, which is also a critical point of the Robin’s function corresponding to the Green’s function of biharmonic operator with the same boundary condition. Similar conclusion has been obtained in [6] under the condition that the domain is strictly convex.展开更多

It is proved that this operator preserves the starlikeness on some domains in Banach spaces but does not preserves convexity for some cases. Moreover, the growth theorem, covering theorem, and the radius of starlikeness are discussed. Some results of Roper and Suffridge, Gong and Liu, Graham et al in C^n are extended to Hilbert spaces or Banach spaces.展开更多

The only condition assumed on μ is a growth condition, namely, there is a constant Co 〉 0 such that for all x ∈ supp(μ) and r 〉 0, μ(B(x, r)) ≤ Cor^n, where 0 〈 n ≤ d.

The only condition assumed on μ is a growth condition, namely, there is a constant Co 〉 0 such that for all x ∈ supp(μ) and r 〉 0, μ(B(x, r)) ≤ Cor^n, where 0 〈 n ≤ d. We prove T1 theorem for non doubling measures with weak kernel conditions. Our approach yields new results for kernels satisfying weakened regularity conditions, while recovering previously known Tolsa's results.
