Descriptions. SL(2,R) is the group of all linear transformations of R2 that preserve oriented area. It is isomorphic to the symplectic group Sp(2,R) and the. Definition. The group SL(2,\R) is defined as the group of 2 \times 2 matrices with entries from the field of real numbers and determinant 1. SL2(R) gives the student an introduction to the infinite dimensional representation theory of semisimple Lie groups by concentrating on one example - SL2(R).

derive a product decomposition for SL2(R) and use it to get a concrete image of This formula SL2(R) = KAN is called the Iwasawa decomposition of the group. Topology via remarkable actions. The group SL2(R) and some subgroups. Definition. The group SL2(R) is the group of 2 × 2 real matrices of determinant 1. This essay will explain what is needed about representations of SL2(R) in the elementary parts of the theory of automorphic forms. On the.

As for what group it is, well, it's the universal cover of S L (n, R). Since it's not a matrix group, you probably haven't encountered it before. You'll just have to. The representations of the group SL(2,R) were originally studied by Bargmann  , and The corresponding Lie algebra is denoted by sl2(C). G = SL2(R). A = {[ a 0. 0 1/a. ]} w = [. 0 −1. 1. 0. ] N = {[. 1 x. 0 1. ]} P = {[. a x. 0 1/a. ]} = AN. P = {[ a 0 x 1/a. ]} = AN. K = {[ cosθ −sinθ sinθ cosθ. ]} 3. We will follow Lang's SL2(R) and it is mainly an introduction through SL2(R) to the infinite dimensional representation theory of semisimple Lie groups. We don't .
