Abstract
Upper semilattice of binary strings with the relation ``x is simple conditional to y'' Andrei Muchnik, Andrei Romashchenko, Alexander Shen, Nikolai Vereshagin We study the properties of the set of binary strings with the relation ``the Kolmogorov complexity of x conditional to y is small''. We prove that there are pairs of strings which have no greatest common lower bound with respect to this preorder. We present several examples when the greatest common lower bound exists but its complexity is much less than mutual information (extending G'acs and K¨orner result).
