On the harmonic extension approach to fractional powers in Banach spaces
, 2020 We show that fractional powers of general sectorial operators on Banach spaces can be obtained by the harmonic extension approach. Moreover, for the corresponding second order ordinary differential equation with incomplete data describing the harmonic ...

On an atomic decomposition in Banach spaces [PDF]
Sahand Communications in Mathematical Analysis, 2018 An atomic decomposition is considered in Banach space. A method for constructing an atomic decomposition of Banach space, starting with atomic decomposition of subspaces is presented. Some relations between them are established.

The Approximation of Harmonic Functions by Harmonic Polynomials and by Harmonic Rational Functions [PDF]
Bulletin of the American Mathematical Society, 1929 which converges uniformly f or all values of 6. This is of course a general fact, tha t if a given function can be uniformly approximated as closely as desired by a linear combination of other functions, then that function can be expanded in a uniformly convergent series of which each term is a linear combination of those other functions, and ...

Harmonic analysis of harmonic functions in the plane [PDF]
Proceedings of the American Mathematical Society, 1976 A continuous function on the complex plane is harmonic if and only if the span of its compositions with entire functions is not dense in the space of continuous functions in the topology of uniform convergence on compact sets.

Harmonic hybrid inflation [PDF]
Journal of High Energy Physics, 2020 AbstractWe present a mechanism for realizing hybrid inflation using two axion fields with a purely non-perturbatively generated scalar potential. The structure of the scalar potential is highly constrained by the discrete shift symmetries of the axions.

ON HARMONICITY IN A DISC AND n-HARMONICITY [PDF]
Bulletin of the Korean Mathematical Society, 2010 Let ? 6 -0 be either a power bounded radial measure with compact support on the unit disc D with ?(D) = 1 such that there is a - > 0 so that |ˆ(s)| 6 1 for every s 2 §(-) \ {0,1}, or just a radial probability measure on D. Here, we provide a decomposition of the set X = {h 2 L 1 (D) | limn!1 h ⁄ ? n exists}.
