**Areas of mathematics**

Let us list here rooms which serve for discussions related to a specific area of mathematics.

 * [Calculus and analysis](https://chat.stackexchange.com/rooms/info/14150/calculus-and-analysis) is a room which is intended for all areas which broadly fall under analysis (calculus, real analysis, functional analysis, complex analysis, ...). (Some of this areas had a separate rooms in the past, but they did not generate enough interest.)
 * [General Topology](https://chat.stackexchange.com/rooms/info/15201/general-topology)
 * [Geometry & Topology](https://chat.stackexchange.com/rooms/info/20807/geometry-topology) is a room for discussions various areas related to geometry and topology (algebraic topology and differential topology, differential geometry, homological algebra, homotopy theory, ...) Originally some of these areas had separate rooms which were users only by were few users - you can find pointers to discussions about creating a single room [here](https://chat.stackexchange.com/rooms/20807/conversation/expanding-scope-of-the-room) and [here](https://chat.stackexchange.com/rooms/20807/conversation/expanding-scope-of-the-room-more-links).
 * [Linear & Abstract algebra](https://chat.stackexchange.com/rooms/info/13473/linear-abstract-algebra) - as the name of the room suggests, this is for discussion of topics from linear algebra and abstract algebra.
 * [Number Theory](https://chat.stackexchange.com/rooms/info/12070/number-theory)
 * [Set Theory](https://chat.stackexchange.com/rooms/info/2318/set-theory) - this room is intended for anything related to set theory.
