One-Parameter Families of Operators in $\mathbb{C}$

Complex Variables 2007-05-23 v2

Abstract

We develop classes of one-parameter families (OPF) of operators on Cc(C)C^\infty_c(\mathbb{C}) which characterize the behavior of operators associated to the ˉ\bar\partial-problem in L2(C,e2p)L^2(\mathbb{C},e^{-2p}) where pp is a subharmonic, nonharmonic polynomial. We prove that an order 0 OPF operator extends to a bounded operator from Lq(C)L^q(\mathbb{C}) to itself, 1<q<1<q<\infty, with a bound that depends on qq and the degree of pp but not on the parameter τ\tau or the coefficients of pp. Last, we show that there is a one-to-one correspondence given by the partial Fourier transform in τ\tau between OPF operators of order m2m\leq 2 and nonisotropic smoothing (NIS) operators of order m2m\leq 2 on polynomial models in C2\mathbb{C}^2.
