Weak Type Estimates for Singular Integrals Related to a Dual Problem of Muckenhoupt–Wheeden
نویسندگان
چکیده
A well-known open problem of Muckenhoupt–Wheeden says that any Calderón–Zygmund singular integral operator T is of weak type (1,1) with respect to a couple of weights (w,Mw). In this paper, we consider a somewhat “dual” problem: sup λ>0 λw { x ∈Rn : |Tf (x)| Mw > λ } ≤ c ∫

A1 Conjecture: Weak Norm Estimates of Weighted Singular Operators and Bellman Functions
We consider several weak type estimates for dyadic singular operators using the Bellman function approach. We disprove the A1 conjecture, which is a weaker statement than Muckenhoupt–Wheeden conjecture.
متن کاملTHE GROWTH OF THE Ap CONSTANT ON CLASSICAL ESTIMATES
We survey on some recent results concerning weak and strong weighted L estimates for Calderón-Zygmund operators with sharp bounds when the weight satisfies the A1 condition. These questions are related to a problem posed by Muckenhoupt and Wheeden in the seventies.
متن کاملMATRIX Ap WEIGHTS VIA MAXIMAL FUNCTIONS
Weighted Norm theory forms a basic component of the study of singular integrals. Here one attempts to characterize those measure spaces over which a broad class of singular integral operators remain bounded. For the case of singular integral operators on C-valued functions in Euclidean space, the answer is given by the Hunt-Muckenhoupt-Wheeden theorem [10]. It states that the necessary and suff...
متن کاملA General New Algorithm for Regulaization of Singular Integrals in Three-Dimensional Boundary Elemnts
In this paper an algorithm is presented for the regularization of singular integrals with any degrees of singularity, which may be employed in all three-dimensional problems analyzed by Boundary Elements. The integrals in Boundary Integrals Equations are inherently singular. For example, one can mention the integrals confronted in potential problems to evaluate the flow or the gradient of the f...
