proof

let a be Point of I[01]; :: according to BORSUK_1:def 1 :: thesis:
let G be a_neighborhood of (LoopMlt (f,g)) . a; :: thesis:
(LoopMlt (f,g)) . a = (f . a) * (g . a) by Def2;
then consider A being open a_neighborhood of f . a, B being open a_neighborhood of g . a such that
A2: A * B c= G by TOPGRP_1:37;
consider Ha being a_neighborhood of a such that
A3: f .: Ha c= A by BORSUK_1:def 1;
consider Hb being a_neighborhood of a such that
A4: g .: Hb c= B by BORSUK_1:def 1;
reconsider H = Ha /\ Hb as a_neighborhood of a by CONNSP_2:2;
take H ; :: thesis:
(LoopMlt (f,g)) .: H c= A * B

proof

let y be object ; :: according to TARSKI:def 3 :: thesis:
assume y in (LoopMlt (f,g)) .: H ; :: thesis:
then consider c being Element of I[01] such that
A5: c in H and
