%0 Journal Article %T On the global monodromy of a Lefschetz fibration arising from the Fermat surface of degree 4 %A Yusuke Kuno %J Mathematics %D 2008 %I arXiv %X A complete description of the global monodromy of a Lefschetz fibration arising from the Fermat surface of degree 4 is given. As a by-product we get a positive relation among right hand Dehn twists in the mapping class group of a closed orientable surface of genus 3. %U http://arxiv.org/abs/0811.3274v3
