theorem
0.(RLSp_LpFunct(M,k)) = X-->0 &
0.(RLSp_LpFunct(M,k)) in AlmostZeroLpFunctions(M,k)
proof
   thus 0.(RLSp_LpFunct(M,k)) = X --> 0 by Th23,SUBSET_1:def 8;
A1:X-->0 a.e.= X-->0,M & X --> 0 in Lp_Functions(M,k) by Th23,LPSPACE1:28;
   0.(RLSp_LpFunct(M,k)) = 0.(RLSp_PFunctX) by Th23,SUBSET_1:def 8;
   hence 0.(RLSp_LpFunct(M,k)) in AlmostZeroLpFunctions(M,k) by A1;
end;
