Abstract
We study the state complexity of boolean operations, concatenation, and star, with one or two of the argument languages reversed. We derive tight upper bounds for the symmetric differences and differences of such languages. We prove that the previously discovered bounds for union, intersection, concatenation and star of such languages can all be met by the recently introduced universal witness and its variants.
This work was supported by the Natural Sciences and Engineering Research Council of Canada under grant No. OGP0000871, and was done while the second author was at the University of Waterloo.
