let f be FinSequence of (TOP-REAL 2); :: thesis: for p being Point of (TOP-REAL 2) st f is unfolded holds

f -: p is unfolded

let p be Point of (TOP-REAL 2); :: thesis: ( f is unfolded implies f -: p is unfolded )

f -: p = f | (p .. f) by FINSEQ_5:def 1;

hence ( f is unfolded implies f -: p is unfolded ) ; :: thesis: verum
