and now im incapable of handling romantic interpersonal connections

Damn, I’m sorry that happened Log in to see images! Just remember you can always come here for unconditional support.

Also if this is trauma vent thread then my ex-partner of four years sexually and emotionally abused me for the majority of the relationship and now I can’t engage intimacy with another person without having panic attacks, resulting in my feeling inadequate and distancing myself until they break up with me.

Let G be a connected, simply connected compact Lie group, for example the special unitary group SU(n), and let Γ be a finite subgroup of G. Then the homogeneous space X = G/Γ has fundamental group Γ, which acts by right multiplication on the universal covering space G. Among the many variants of this construction, one of the most important is given by locally symmetric spaces X = Γ\G/K, where

G is a non-compact simply connected, connected Lie group (often semisimple),

K is a maximal compact subgroup of G

Γ is a discrete countable torsion-free subgroup of G.

In this case the fundamental group is Γ and the universal covering space G/K is actually contractible (by the Cartan decomposition for Lie groups).

As an example take G = SL(2, R), K = SO(2) and Γ any torsion-free congruence subgroup of the modular group SL(2, Z).

From the explicit realization, it also follows that the universal covering space of a path connected topological group H is again a path connected topological group G. Moreover, the covering map is a continuous open homomorphism of G onto H with kernel Γ, a closed discrete normal subgroup of G:

{\displaystyle 1\to \Gamma \to G\to H\to 1.} 1\to \Gamma \to G\to H\to 1.

Since G is a connected group with a continuous action by conjugation on a discrete group Γ, it must act trivially, so that Γ has to be a subgroup of the center of G. In particular π1Log in to see images! = Γ is an abelian group; this can also easily be seen directly without using covering spaces. The group G is called the universal covering group of H.

As the universal covering group suggests, there is an analogy between the fundamental group of a topological group and the center of a group; this is elaborated at Lattice of covering groups.

Just checked and yeah not sure my calculator has a bumon for all that.

university math is basically just a really rigorous subfield of philosophy sry guys

lmfaO math is ****in gay
