Idea About Why USTCON Is SL-complete
The most important Complete Problem is the USTCON, Lewis and Papadimitriou by their definition showed that USTCON is complete for SL class. They constructed a nondeterministic machine for USTCON, and they made a lemma for converting this machine into Symmetric Turing Machine. Then the theorem follows as any language can be accepted using a symmetric Turing machine is logspace reducible to USTCON as from the properties of the symmetric computation we can view the special configuration as the undirected edges of the graph.
