WebWe study the question whether the Hilbert cube Q is Lipschitz homogeneous. The answer … WebDec 12, 2013 · Indeed, the Hilbert cube, i.e., the countable infinite product of copies of the unit interval ${\mathbb {I}}= [0,1]$is such an example. It is homogeneous by Kellers’s Theorem from [101], but does not admit the structure of a topological group since it has the fixed-point property.

The Hilbert polynomial hλ(t) of the coordinate algebra of πλ: X ֒→ P(V) factors as the product hλ(t) = Y α (1+cλ(α)t). This product is taken over the set of positive roots α of G which satisfy hλ,α∨i 6= 0; the number d of such roots is equal to the dimension of X. " - Hilbert cube is homogeneous
