Abstract: In a recent work, Beierle, Brinkmann and Leander presented a recursive tree search for finding APN permutations with linear self-equivalences in small dimensions. In this paper, we describe ...

Among the most powerful tools we have as programmers—perhaps the most powerful tools—are functions. We’ve already seen some built-in Python functions, for example, print() and type(). We’ll see many ...

WITH the exception of certain corrections and additions, the fourth edition of this comprehensive work differs in no material respect from the third edition published in 1920. “Whittaker and Watson” ...

A NOTICE of the “Treatise on the Theory of Functions,” by Profs. Harkness and Morley, appeared in NATURE during 1894 (vol. xlix. p. 477). The object of that work, as of Prof. Forsyth's book on the ...

A generic function object contains a set of methods, a lambda-list, a method combination type, and other information. Like an ordinary Lisp function, a generic function takes arguments, performs a ...

Abstract: We introduce a new class of quadratic functions based on a hierarchy of linear time-varying (LTV) dynamical systems. These quadratic functions in the higher order space can be also seen as a ...

Quadratic functions are essential in the world of mathematics and have a wide range of applications in various fields, such as physics, engineering, and finance. An inverse function can be thought of ...

Introduction: Memorizing the entire Qur’an is a vast undertaking that has been accomplished by many devoted Muslims throughout history. This religious text, comprising 114 ...
