THIS book, like the kindred work of Prof. Byerly on “Fourier's Series and Spherical Harmonics,” marks the modern system of mathematical treatment, and may be contrasted with Dr. Todhunter's “Functions ...

Geometric Function Theory is a vibrant field that investigates the geometric properties of analytic functions, including univalence, starlikeness, and convexity, which are key to understanding their ...

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

The Hadamard expansion procedure applied to Laplace-type integrals taken along contours in the complex plane enables an exact description of the method of steepest ...
