  9. Length function - Wikipedia

    en.wikipedia.org/wiki/Length_function

    A group with a length function does not form a filtered group, meaning that the sublevel sets:= {()} do not form subgroups in general. However, the group algebra of a group with a length functions forms a filtered algebra : the axiom L ( g h ) ≤ L ( g ) + L ( h ) {\displaystyle L(gh)\leq L(g)+L(h)} corresponds to the filtration axiom.
