In mathematics, the modular group is the projective special linear group (,) of 2 × 2 matrices with integer coefficients and determinant 1. The matrices A and − A are identified. The modular group acts on the upper-half of the complex plane by fractional linear transformations , and the name "modular group" comes from the relation to ...
The braid group B 3 is the universal central extension of the modular group. Under this covering, the preimage of the modular group PSL(2, Z) is the braid group on 3 generators, B 3, which is the universal central extension of the modular group. These are lattices inside the relevant algebraic groups, and this corresponds algebraically to the ...
In mathematics, a modular invariant of a group is an invariant of a finite group acting on a vector space of positive characteristic (usually dividing the order of the group). The study of modular invariants was originated in about 1914 by Dickson (2004) .
In mathematics, and more precisely in topology, the mapping class group of a surface, sometimes called the modular group or Teichmüller modular group, is the group of homeomorphisms of the surface viewed up to continuous (in the compact-open topology) deformation.
Thus their quotient, and therefore j, is a modular function of weight zero, in particular a holomorphic function H → C invariant under the action of SL(2, Z). Quotienting out by its centre { ±I } yields the modular group, which we may identify with the projective special linear group PSL(2, Z).
The modular group SL(2, Z) acts on the upper half-plane by fractional linear transformations.The analytic definition of a modular curve involves a choice of a congruence subgroup Γ of SL(2, Z), i.e. a subgroup containing the principal congruence subgroup of level N for some positive integer N, which is defined to be

The company was founded by two MIT graduates, Ray Stata and Matthew Lorber in 1965. [9] The same year, the company released its first product, the model 101 op amp, [10] which was a hockey-puck sized module used in test and measurement equipment. [11] In 1967, the company published the first issue of its technical magazine, Analog Dialogue. [12]
