Spiral like integral operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
In this paper we investigate the Robertson-Libera integral operators for the class of spiral like univalent and analytic functions. We find that special types of transformations preserve the class property.

Rough Marcinkiewicz integral operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We study the Marcinkiewicz integral operator M𝒫f(x)=(∫−∞∞|∫|y|≤2tf(x−𝒫(y))(Ω(y)/|y|n−1)dy|2dt/22t)1/2, where 𝒫 is a polynomial mapping from ℝn into ℝd and Ω is a homogeneous function of degree zero on ℝn with mean value zero over the unit sphere Sn−1. We

COMPOSITE OPERATORS AS INTEGRATION VARIABLES IN BEREZIN INTEGRALS [PDF]

open access: yesModern Physics Letters A, 1995
We define nonlinear changes of variables in Berezin integrals as new integration variables of homogeneous polynomials of the defining elements in the Grassmann algebra. We perform such a change of variables in the partition function of QCD by introducing as integration variables cubic and quadratic polynomials of the quark field, with the quantum ...
