This page is about Topological Rings in the context of topology. For other uses, see Definition:Ring.


Let $\struct{R, +, \circ}$ be a ring.

Let $\tau$ be a topology over $R$.

Then $\struct{R,+,\circ,\tau}$ is a topological ring if and only if:

$(1): \quad \struct{R, +, \tau}$ is a topological group
$(2): \quad \struct{R, \circ,\tau}$ is a topological semigroup.
