comment How to check numerically iterated logarithm law ? (How to choose cutOff lim_n sup_{m: n<= m<= CutOff} ) ?
@IosifPinelis Thank you for your comments. Still I am curious can one numerically test LIL ?

comment Center of $U_q(sl_3)$ and $U_q(sl_4)$
@JimHumphreys Capelli type expressions also work for all classical Lie algebras - that was done by Japanese people related to Umeda, more unified treatment via Yangians given by Molev Olashanky Nazarov (but it sometimes less explicit). In general that is related to many physicts works since similar expressions describe quantum commuting hamiltonians and physicists "like" explicit formulas ...

comment Center of $U_q(sl_3)$ and $U_q(sl_4)$
@JimHumphreys concerning "it's tricky to write homogeneous generators of the center of the enveloping algebra of higher degree than the Casimir operator" I would say that currently it is more or less well-understood, how to write nice formulas for generators: there are Capelli determinants/permanents and even Okounkov's immanants which give linear basis in the center - not only generators...

Thank you very much very helpful answer ! May be it is worth to link Universal C*-algebra en.wikipedia.org/wiki/Universal_C*-algebra if you consider it well enough written.
