Positive Dehn Twist Expressions for some New Involutions in the Mapping Class Group II

Abstract

The positive Dehn twist expressions for the generalizations of the new involutions described in math.GT/0404310 are presented. The homeomorphism types of the Lefschetz fibrations that they define are determined for several examples.
