Congruence (general relativity) — In general relativity, a congruence (more properly, a congruence of curves) is the set of integral curves of a (nowhere vanishing) vector field in a four dimensional Lorentzian manifold which is interpreted physically as a model of spacetime.… … Wikipedia
Zeller's congruence — is an algorithm devised by Christian Zeller to calculate the day of the week for any Julian or Gregorian calendar date. Formula For the Gregorian calendar, Zeller s congruence is:h = left(q + leftlfloorfrac{(m+1)26}{10} ight floor + K +… … Wikipedia

Neopolarogram — mathematical relation of current, charge and fractional derivatives. The term Neopolarogram refers to mathematical derivatives of polarograms or cyclic voltammograms that in effect deconvolute diffusion and electrochemical kinetics. This is… … Wikipedia
Modular group — For a group whose lattice of subgroups is modular see Iwasawa group. In mathematics, the modular group Γ is a fundamental object of study in number theory, geometry, algebra, and many other areas of advanced mathematics. The modular group can be… … Wikipedia
Ideal (ring theory) — In ring theory, a branch of abstract algebra, an ideal is a special subset of a ring. The ideal concept allows the generalization in an appropriate way of some important properties of integers like even number or multiple of 3 . For instance, in… … Wikipedia
Raychaudhuri equation — In general relativity, Raychaudhuri s equation is a fundamental result describing the motion of nearby bits of matter.The equation is important as a fundamental lemma for the Penrose Hawking singularity theorems and for the study of exact… … Wikipedia
Modular curve — In number theory and algebraic geometry, a modular curve Y(Γ) is a Riemann surface, or the corresponding algebraic curve, constructed as a quotient of the complex upper half plane H by the action of a congruence subgroup Γ of the modular group of … Wikipedia
