Modulus is the diminutive from the Latin word modus meaning measure or manner. It, or its plural moduli, may refer to the following:
Physics, engineering and computing
- Moduli (physics), scalar fields for which the potential energy function has continuous families of global minima
- The measurement of standard pitch in the teeth of a rotating gear
- Bulk modulus, a measure of compression resistance
- Elastic modulus, a measure of stiffness
- Young's modulus, a specific elastic modulus
- The modulo operator (
%,mod, etc.) of various programming languages
Mathematics
- Modulus (modular arithmetic), base of modular arithmetic
- Modulus, the absolute value of a real or complex number ( |a| )
- Moduli space, in mathematics a geometric space whose points represent algebro-geometric objects
- Conformal modulus, a measure of the size of a curve family
- Modulus of continuity, a function gauging the uniform continuity of a function
- Similarly, the modulus of a Dirichlet character
- Modulus (algebraic number theory), a formal product of places of a number field
- The modular function in the theory of Haar measure, often called simply the modulus
Other uses
