Let G be a finite group and B-D2o-D2 (G) be the Principal 3-block of G (over a complete values ring)。我们提出了一个遵循的理论(Morita equivalence意味着拥有相同的模块类别)。(1) If q ≡ 2, 5 (mod 9), then the (groups PGU(3,qイD12イエD1) have the same Brauer category and BイD20イエD2 (PGU(3,qイD12イエD1)) and BイD20イエD2(PGU(3,2イD12イエD1)) are Morita equivalent。(2) If q ≡ 4, 7 (mod9), then the (groups PGL(3,q) have the same Brauer category and BイイD20イエD2(PGL(3,q) and BイD20イエD2(PGL(3,4) are Morita equivalent。(3) If q ≡ 2, 5 (mod 9), then the (groups SU(3,qイD12イエD1) have the same Brauer category and BイD20イエD2 (SU(3,qイD12イエD1)) and BイD20イエD2(SU(3,2イイD12イエD1)) are Morita equivalent。(4) If q ≡ 4, 7 (mod9), then the (groups SL(3,q) have the same Brauer category and BイイD20イエD2(SL(3,q)) and BイD20イD2(SL(3,2) are Morita equivalent。(5) If q ≡ 2, 5 (mod 9), then the (groups GU(3,qイD12イエD1) have the same Brauer category and BイD20イエD2 (GU(3,qイD12イエD1)) and BイD20イエD2(GU(3,2イD12イエD1)) are Morita equivalent。(6) If q ≡ 4, 7 (mod9), then the (groups GL(3,q) have the same Brauer category and BイイD20イエD2 (GL(3,q) and BイD20イD2(GL(3,4) are Morita equivalent。(7) If q ≡ 2, 5 (mod 9), then the (groups GイイD12イエD1(q) have the same Brauer category and BイD20イエD2 (GイD12イエD1)(q) and BイD20イエD2(GイD12イエD1)(2) are Morita equivalent。
英文摘要
Let G be a finite group and BィイD2oィエD2 (G) be the principal 3-block of G (over a complete valuation ring). We proved the follwing theorem ( , were Morita equivalence means having the same module category).Theorem.(1) If q ≡ 2, 5 (mod 9), then the (groups PGU(3,qィイD12ィエD1) have the same Brauer category and BィイD20ィエD2 (PGU(3,qィイD12ィエD1)) and BィイD20ィエD2(PGU(3,2ィイD12ィエD1)) are Morita equivalent.(2) If q ≡ 4, 7 (mod 9), then the (groups PGL(3,q) have the same Brauer category and BィイD20ィエD2 (PGL(3,q) and BィイD20ィエD2(PGL(3,4) are Morita equivalent.(3) If q ≡ 2, 5 (mod 9), then the (groups SU(3,qィイD12ィエD1) have the same Brauer category and BィイD20ィエD2 (SU(3,qィイD12ィエD1)) and BィイD20ィエD2(SU(3,2ィイD12ィエD1)) are Morita equivalent.(4) If q ≡ 4, 7 (mod 9), then the (groups SL(3,q) have the same Brauer category and BィイD20ィエD2 (SL(3,q)) and BィイD20ィエD2(SL(3,2) are Morita equivalent.(5) If q ≡ 2, 5 (mod 9), then the (groups GU(3,qィイD12ィエD1) have the same Brauer category and BィイD20ィエD2 (GU(3,qィイD12ィエD1)) and BィイD20ィエD2(GU(3,2ィイD12ィエD1)) are Morita equivalent.(6) If q ≡ 4, 7 (mod 9), then the (groups GL(3,q) have the same Brauer category and BィイD20ィエD2 (GL(3,q) and BィイD20ィエD2(GL(3,4) are Morita equivalent.(7) If q ≡ 2, 5 (mod 9), then the (groups GィイD12ィエD1(q) have the same Brauer category and BィイD20ィエD2 (GィイD12ィエD1)(q) and BィイD20ィエD2(GィイD12ィエD1)(2)) are Morita equivalent.
