Springer basic sets and modular Springer correspondence for classical types

We define the notion of basic set data for finite groups (building on the notion of basic set, but including an order on the irreducible characters as part of the structure), and we prove that the Springer correspondence provides basic set data for Weyl groups. Then we use this to determine explicitly the modular Springer correspondence for classical types (for representations in odd characteristic). In order to do so, we compare the order on bipartitions introduced by Dipper and James with the order induced by the Springer correspondence.Comment: 31 page

Saving People From the Fiery Pits of Hell? A Review of “The Very Worst Missionary”

Excerpt: As a Christian college student several decades ago, I knew without a doubt that the holiest, most sanctified majors on campus where those preparing their graduates for overseas missions. This probably explains the small twinges of guilt I felt when others gushed about their longing to serve God on the mission field. Nothing about that vocation seemed appealing to me, nor did the yearly short-term missions trips the college hosted, when vanloads of students travelled to Mexico or flew to other far-away locales to offer children a week of Vacation Bible School, or to build an outdoor baño
