We implement the arithmetical operations modulo m, such as addition, subtraction, multiplication, and division. Basic concepts of number theory, like the order of an element, quadratic residues, and...doi:10.1007/978-3-642-14764-7_39Jrg ArndtSpringer Berlin Heidelberg...
n. A form of integer arithmetic in which all integers having the same remainder when divided by a given natural number (called the modulus) are considered equivalent: Clocks use modular arithmetic with modulus 12, so 4 hours after 9 o'clock is 1 o'clock. ...

Modular ArithmeticModular arithmetic is the arithmetic of congruences, sometimes known informally as "clock arithmetic." In modular arithmetic, numbers "wrap around" upon reaching a given fixed quantity, which is known as the modulus (which would be 12 in the case of hours on a clock, or 60...
and less arithmetic, and the modular symbols used closed paths in \({\gamma \backslash {\mathbb h}}\) . however, in theorem 1.7 we need to combine statistics from various cusps, since not all rational cusps are equivalent to \(\infty \) for \(\gamma _0(q)\) . moreover, we ...
Montgomery multiplicationand fastmodulo / division / divisibility checksfor when the divisor is constant (which can often be used to speed up modular arithmetic by 5-15x); how to use them in variousfactorization algorithms(upd: fixed link) (writing a 3x-faster-than-state-of-the-art implementati...
They are both very good, but I want to write a more concise blog about the modular inverse specifically, as it is needed in many problems that don't even belong to number theory. The Problem There are two integer numbersAandB. Suppose you know thatAis divisible byB. But they are very...
Image Encryption and Decryption Using Chaotic Maps and Modular Arithmetic In this paper we have proposed a scheme which incorporates the concept of modular arithmetic and chaos theory, for image encryption and decryption.

Modular forms are tremendously important in various areas of mathematics, from number theory and algebraic geometry to combinatorics and lattices. Their Fourier coefficients, with Ramanujan's tau-function as a typical example, have deep arithmetic significance. Prior to this book, the fastest known alg...
Number Theory (2023) 9:71 2.3 Arithmetic invariants It is a standard result that an elliptic curve E/K defined as E : Y 2 = X(X − A)(X + B) with A + B + C = 0 has the corresponding arithmetic invariants E = 24(ABC)2, c4 = 24(AB + BC + AC), jE = −28 (AB ...
