let a, b be real number ; ( a <= b implies for x being Point of (Closed-Interval-TSpace a,b)
for C being Loop of x holds the carrier of (pi_1 (Closed-Interval-TSpace a,b),x) = {(Class (EqRel (Closed-Interval-TSpace a,b),x),C)} )
assume A1:
a <= b
; for x being Point of (Closed-Interval-TSpace a,b)
for C being Loop of x holds the carrier of (pi_1 (Closed-Interval-TSpace a,b),x) = {(Class (EqRel (Closed-Interval-TSpace a,b),x),C)}
let x be Point of (Closed-Interval-TSpace a,b); for C being Loop of x holds the carrier of (pi_1 (Closed-Interval-TSpace a,b),x) = {(Class (EqRel (Closed-Interval-TSpace a,b),x),C)}
let C be Loop of x; the carrier of (pi_1 (Closed-Interval-TSpace a,b),x) = {(Class (EqRel (Closed-Interval-TSpace a,b),x),C)}
Closed-Interval-TSpace a,b is convex
by A1, Th13;
hence
the carrier of (pi_1 (Closed-Interval-TSpace a,b),x) = {(Class (EqRel (Closed-Interval-TSpace a,b),x),C)}
