Mathematical methods and special functions have long served as the backbone of modern theoretical physics and applied mathematics. These tools enable researchers to solve complex differential ...
Recent advances in harmonic analysis have renewed interest in Hausdorff operators and Hardy inequalities, given their central role in understanding the structure of function spaces. Hausdorff ...
The paper deals with the computation of functions of fractional powers of differential operators. The spectral properties of these operators naturally suggest the use of rational approximations. In ...
