章节摘录

版权页：   插图：   The max in the display is achieved for ｜r-s｜≤1. Thus M naive G,{μ},C is not flat for ｜r-s｜>1, as its generic and special fibers have different dimension. We note that the analogous argument given in the proof of [75, Prop. 3.8(b)] should be amended to use the reduced special fiber in place of the honest special fiber. As always, one remedies for non-flatness of the naive local model by defining the honest local model M loc G,{μ),C to be the scheme-theoretic closure in M naive G,{μ},C of its generic fiber. Although less is known about Mloc G,{μ},C for ramified GUn than for ramified ResF/F0 GLn and ReSF/F0 GSp2g, there are by now a number of results that have been obtained in various special cases. In low rank, the case rt = 3 has been completely worked out. Theorem 2.24 ([75, 4.5, 4.15], [80, 6]). Let n=3 and (r, s)=(2,1). (i) Let C be the homothety class of the lattice A0=On F Fn. Then M naive G,{μ},C=M locG,{μ},Cthat is, Mnaive G,{μ},C is flat over Spec OF. Moreover, Mnaive G,{μ},C is normal and Cohen-Macaulay,it is smooth outside a single point y in its special fiber, and its special fiber is integral andnormal and has a rational singularity at y. The blowup Mloc G,{μ},C →Mloc G,{μ},C at y isregular with special fiber a reduced union of two smooth surfaces meeting transversely along a smooth curve. (ii) Let,C=[A1, A2], the lattice chain consisting of the homothety classes of A1 and A2. Then.Mloc G,{μ},C is smooth over Spec OF with geometric special fiber isomorphic to P2.(iii) Let,C be the standard maximal lattice chain in F3. Then Mloc G,{μ},C is normal andCohen-Macaulay. Its special fiber is reduced and consists of two irreducible components,each normal and with only rational singularities, which meet along two smooth curves which, in turn, intersect transversally at a point.
