I'm interested in the crossover of Lie groups/differential geometry and I'm a bit confused about the relation of Lie algebras with symmetric spaces.
Take for instance the Lie group G=SL(2,R), we take the quotient by K=SO(2) as isotropic group(maximal compact subgroup) and get the symmetric space G/K= H2(hyperbolic plane).
How is it then the tangent vector space of the hyperbolic plane exactly related to the Lie algebra sl(2,R) of G (if at all)?
Thanks in advance, I would also be interested in references on introductory textbooks that treat Lie groups from the geometrical side rather than the purely abstract algebraic one.
