Abstract: In the present paper we discuss some recent versions of localization methods for calculations in the groups of points of algebraic-like and classical-like groups. Namely, we describe relative localization, universal localization, and enhanced versions of localization-completion. Apart from the general strategic description of these methods, we state some typical technical results of the conjugation calculus and the commutator calculus. Also, we state several recent results obtained therewith, such as relative standard commutator formulae, bounded width of commutators, with respect to the elementary generators, and nilpotent filtrations of congruence subgroups. Overall, this shows that localization methods can be much more efficient, than expected.

Key words and phrases: unitary groups, Chevalley groups, elementary subgroups, elementary generators, localization, relative subgroups, conjugation calculus, commutator calculus, Noetherian reduction, Quillen–Suslin lemma, localization-completion, commutator formulae, commutator width, nilpotency of $\mathrm K_1$, nilpotent filtration.
