Acyclic list 7-coloring of planar graphs

Theacyclic list chromatic numberof every planar graph is proved to be at most 7. 2002 Wiley Periodicals, Inc. J Graph Theory 40: 83–90, 2002

Frequency Squares of Orders 7 and 8

We enumerate frequency squares of orders 7 and 8 and the corresponding isotopism classes. An error in a previous paper by L.J. Brant and G.L. Mullen is discovered and partially corrected.

M ay 2 00 7 SQUARES OF MENGER - BOUNDED GROUPS

Using a portion of the Continuum Hypothesis, we prove that there is a Menger-bounded (also called o-bounded) subgroup of the Baer-Specker group Z, whose square is not Mengerbounded. This settles a major open problem concerning boundedness notions for groups, and implies that Menger-bounded groups need not be Scheepers-bounded. This also answers some questions of Banakh, Nickolas, and Sanchis.
