Center node: "symmetry of information a closer look"
  Abstract: Symmetry of information establishes a relation between the information that x has about y (denoted I(x : y)) and the information that y has about x (denoted I(y : x)). In classical information theory, the two are exactly equal, but in algorithmical information theory, there is a small excess quantity of information that differentiates the two terms, caused by the necessity of packaging information in a way that makes it accessible to algorithms. It was shown in [Zim11] that in the case of strings with simple complexity (that is the Kolmogorov complexity of their Kolmogorov complexity is small), the relevant information can be packed in a very economical way, which leads to a tighter relation between I(x : y) and I(y : x) than the one provided in the classical symmetry-of-information theorem of Kolmogorov and Levin. We give here a simpler proof of this result, using a suggestion of Alexander Shen. This result implies a van Lambalgen- type theorem for finite strings and plain complexity: If x is c-random and y is c-random relative to x, then xy is O(c)-random. We show that a similar result holds for prefix-free complexity and weak-K-randomness.
