A class of generalized convex functions, the hyperbolic-concave functions, is defined, and used to characterize the collection of Hardy-Littlewood maximal functions. These maximal functions and the ...
In the paper, the authors present several inequalities for bounding the sums of two sine cardinal functions and the sums of two hyperbolic sine cardinal functions. These inequalities improve ...
THE object of the authors of this volume of mathematical tables is “to supply a comprehensive set of tables of the numerical values of the elementary functions which are in constant use in mathematics ...
