Context: <response>: For any constant c. Matrix groups wey dey over dis fields dey fall under dis regime, as well as adele rings and adelic algebraic groups, wey dey important for number theory. Galois groups of infinite field extensions like the absolute Galois group fit also get topology, wey dem dey call Krull topology, wey dey important to generalize the connection of fields and groups to infinite field extensions wey we don talk. An advanced generalization of dis idea, wey dem adapt to the needs of algebraic geometry, na the étale fundamental group.
