The Hilbert transform is an mathematical object intimately related to physical situations such as charge distribution. It and related objects such as the Cauchy transform, occur in a range of analytical questions, from orthogonal polynomials to dynamics, to analytic function spaces and partial differential equations. The two-weight problem for the Hilbert transform concerns a characterization of those pairs of measures so that the transform maps Hilbert space of one measure into Hilbert space of the other. This problem has been solved by the proposer, Eric T Sawyer and Ignacio Uriate-Tuero, in work sponsored by the National Science Foundation. This has immediate application to for instance a long-standing conjecture of Sarason in operator theory. The goal of this proposal, is to build upon this success, turning to extensions of this characterization for other natural questions, such as that for the Cauchy transform, which is fundamental for the theory of analytic function spaces. This work seeks to detail subtle properties of transforms which closely model physical situations, such as electrical charge distributions. As such, the techniques will impact the range of analytical tools that can be brought to bear on these questions that entail fine knowledge about these operators. In addition, the proposer carries out a variety of roles in mentoring and training a next generation of scientific workforce. This includes: (1) The work of the investigator on an MCTP grant to recruit and train talented undergraduate majors at the Georgia Institute of Technology. (2) Directing two graduate students in their thesis work. (3) Mentoring a number of postdoctoral fellows. (4) Conference organization at research centers in the US, Canada and Europe. (5) Editorial work for the Proceedings of the American Mathematical Society and the Journal of Geometric Analysis. (6) Dissemination of research accomplishments and goals, including lectures at venues around the world.

希尔伯特变换是与电荷分布等物理情况密切相关的数学对象。 它和柯西变换等相关对象出现在一系列分析问题中，从正交多项式到动力学，再到解析函数空间和偏微分方程。希尔伯特变换的双权重问题涉及这些测度对的表征，以便变换将一个测度的希尔伯特空间映射到另一个测度的希尔伯特空间。 这个问题已由提议者 Eric T Sawyer 和 Ignacio Uriate-Tuero 在国家科学基金会资助的工作中得到解决。这可以直接应用到例如算子理论中萨拉森的长期猜想。该提案的目标是在这一成功的基础上，转向对其他自然问题的这种表征的扩展，例如柯西变换，它是分析函数空间理论的基础。 这项工作旨在详细描述变换的微妙属性，这些变换密切模拟物理情况，例如电荷分布。因此，这些技术将影响分析工具的范围，这些工具可以用来解决这些问题，而这些问题需要对这些操作员有深入的了解。此外，提议者在指导和培训下一代科学劳动力方面发挥着各种作用。这包括： (1) 研究者在 MCTP 拨款中开展的工作，以招募和培训佐治亚理工学院的本科专业人才。 （2）指导两名研究生的论文工作。 （三）指导博士后多名。 (4) 美国、加拿大和欧洲研究中心的会议组织。 (5) 《美国数学会会刊》和《几何分析杂志》的编辑工作。 (6) 传播研究成果和目标，包括在世界各地举办讲座。
