Circular Convolution and Product Theorem for Affine Discrete Fractional Fourier Transform
Amir R. Nafchi, Eric Hamke, Cristina Pereyra +1
The Fractional Fourier Transform is a ubiquitous signal processing tool in basic and applied sciences. The Fractional Fourier Transform generalizes every property and application o…
A note on weak factorization of Meyer-type Hardy space via Cauchy integral operator
Yongsheng Han, Ji Li, Cristina Pereyra +1
This paper provides a weak factorization for the Meyer-type Hardy space , and characterizations of its dual and its predual ${\rm VMO}_…
Sharp bounds for general commutators on weighted Lebesgue spaces
Daewon Chung, Cristina Pereyra, Carlos Perez
We show that if an operator T is bounded on weighted Lebesgue space L^2(w) and obeys a linear bound with respect to the A_2 constant of the weight, then its commutator [b,T] with a…
Paraexponentials, Muckenhoupt weights, and resolvents of paraproducts
Cristina Pereyra, Lesley Ward
We analyze the stability of Muckenhoupt's $\RHp$ and $\Ap$ classes of weights under a nonlinear operation, the $\lb$-operation. We prove that the dyadic doubling reverse Hölder cla…
