The book "Double Hilbert Transforms" by S. K. Patel offers a comprehensive analysis of the Lp-bounds of double Hilbert transforms in one and three dimensions, associated with polynomials in two real variables. The Hilbert transform is considered a classic example of a singular integral operator, whose properties and applications in mathematics are extensive. This scholarly work thoroughly investigates the relationship between the monomials of a given polynomial and the boundedness of the corresponding double Hilbert transform. The author highlights the challenges encountered when studying operators whose kernels are supported along curves or surfaces and discusses current research findings in this area. The book is aimed at professionals and students seeking a deeper understanding of the mathematical foundations and the latest developments in the theory of Hilbert transforms.
