for E, F, G being RealNormSpace ex B being Lipschitzian BilinearOperator of (R_NormSpace_of_BoundedLinearOperators (E,F)),(R_NormSpace_of_BoundedLinearOperators (F,G)),(R_NormSpace_of_BoundedLinearOperators (E,G)) st
for u being Point of (R_NormSpace_of_BoundedLinearOperators (E,F))
for v being Point of (R_NormSpace_of_BoundedLinearOperators (F,G)) holds B . (u,v) = v * u
