The resulting dictionary between two dimensional planar shapes with a degree of shade and Hilbert space operators turns out to be illuminating and beneficial for both sides. An exponential transform, essentially a Riesz potential at critical exponent, is at the heart of this novel framework; its best rational approximants unveil a new class of complex orthogonal polynomials whose asymptotic distribution of zeros is thoroughly studied in the text. Connections with areas of potential theory, approximation theory in the complex domain and fluid mechanics are established. The text is addressed, with specific aims, at experts and beginners in a wide range of areas of current interest: potential theory, numerical linear algebra, operator theory, inverse problems, image and signal processing, approximation theory, mathematical physics.Lecture Notes in Mathematics,0075-8434 ;2199Functions of complex variablesOperator theoryPotential theory (Mathematics)Numerical analysisFunctions of a Complex Variablehttps://scigraph.springernature.com/ontologies/product-market-codes/M12074Operator Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/M12139Potential Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/M12163Numerical Analysishttps://scigraph.springernature.com/ontologies/product-market-codes/M14050Functions of complex variables.Operator theory.Potential theory (Mathematics).Numerical analysis.Functions of a Complex Variable.Operator Theory.Potential Theory.Numerical Analysis.515.7246Gustafsson Björnauthttp://id.loc.gov/vocabulary/relators/aut721273Putinar Mihaiauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910257379203321Hyponormal Quantization of Planar Domains2039123UNINA
