Extremal Ω-plurisubharmonic Functions as Envelopes of Disc Functionals
For each closed, positive (1, 1)-current ω on a complex manifold X and each ω-upper semicontinuous function φ on X we associate a disc functional and prove that its envelope is equal to the supremum of all ω-plurisubharmonic functions dominated by φ. This is done by reducing to the case where ω has a global potential. Then the result follows from Poletsky’s theorem, which is the special case ω ...
متن کاملEstimates for continuity envelopes and approximation numbers of Bessel potentials
In this paper we study spaces of Bessel potentials in n-dimensional Euclidean spaces. They are constructed on the basis of a rearrangement-invariant space (RIS) by using convolutions with Bessel-MacDonald kernels. Specifically, the treatment covers spaces of classical Bessel potentials. We establish two-sided estimates for the corresponding modulus of smoothness of order k ∈ N, ωk(f ; t), and d...
متن کاملContinuity envelopes and sharp embeddings in spaces of generalized smoothness
We study continuity envelopes in spaces of generalized smoothness B ,N p,q (R n) and F σ ,N p,q (R n). The results are applied in proving sharp embedding assertions in some limiting situations. © 2008 Elsevier Inc. All rights reserved.
متن کاملValuations and plurisubharmonic singularities
We extend to higher dimension our valuative analysis of singularities of psh functions started in [FJ2]. Following [KoSo], we describe the geometry of the space V of all normalized valuations on C[z1, . . . , zn] centered at the origin. It is a union of simplices naturally endowed with an affine structure. Using relative positivity properties of divisors living on modifications of C n over the ...
متن کاملMaximal Plurisubharmonic Models
An analytic pair of dimension n and center V is a pair (V,M) where M is a complex manifold of (complex) dimension n and V ⊂ M is a closed totally real analytic submanifold of dimension n. To an analytic pair (V,M) we associate the class U (V,M) of the functions u : M → [0,π/4[ which are plurisubharmonic in M and such that u(p)= 0 for each p ∈ V . If U (V,M) admits a maximal function u, the trip...
