Category:Composite of Continuous Mappings is Continuous

This category contains pages concerning Composite of Continuous Mappings is Continuous:

Let $T_1, T_2, T_3$ be topological spaces.

Let $f: T_1 \to T_2$ and $g: T_2 \to T_3$ be continuous mappings.

Then the composite mapping $g \circ f: T_1 \to T_3$ is continuous.
