The Left Cells With A=5, 6 In Affine Weyl Group (?)8 | Posted on:2009-07-06 | Degree:Master | Type:Thesis | Country:China | Candidate:Q Huang | Full Text:PDF | GTID:2120360245474050 | Subject:Basic mathematics | Abstract/Summary: | PDF Full Text Request | In the paper,we study certain left cells in the affine Weyl group (?)8.Moreprecisely,we study the left cells in the two-sided cell W5 with a(W5)=5 and oneof two two-sided cellsΩwith a(Ω)=6 (written W61).We find a representative setof left cells in W5 and W61,and draw the corresponding left cells graphs.We provethat all the left cells in W5 and W61 are left-connected,verifying a conjecture ofLusztig in our case.Finally,we find all the distinguished involutions of (?)8 in W5and W61.
