Path connected

Definition (Path connected)

A Topological Space (X,T)(X,\mathscr{T}) is path connected if, for x1,x2Xx_{1},x_{2}\in X, there exists a continuous map γ:[0,1]X\gamma:[0,1]\to X for which γ(0)=x1 and γ(1)=x2\gamma(0)=x_{1}\text{ and }\gamma(1)=x_{2}

Definition (Locally path connected)

A Topological Space (X,T)(X,\mathscr{T}) is locally path connected if, for each xXx\in X and for each Neighbourhood U\mathcal{U} of xx, there exists a neighbourhood V\mathcal{V} of xx such that if x1,x2Vx_{1},x_{2}\in \mathcal{V} then there exists a continuous map γ:[0,1]U\gamma:[0,1]\to \mathcal{U} for which γ(0)=x1 and γ(1)=x2\gamma(0)=x_{1}\text{ and }\gamma(1)=x_{2}

Remark

If (X,T)(X,\mathscr{T}) is connected and Locally path connected, then it is .
