The teaching of judicial documents emphasizes on practice,we need to change the thinking,break the originally traditional teaching pattern,reschedule the teaching content,design the teaching link,use the case teaching flexibly on the condition of material,and teach students with the move process of laws so as to adapt for the judicial practice.
The article' s chapter four mainly introduces "the first plea bargaining case in china" and its significance, and compares the plea bargaining procedure with Chinese summary procedure and simplified common procedure.
In the present paper we study the remaing nontrivial case, that of a negative central charge-N.
The method applies to the standard arithmetic subgroups ofSO(n,1) (a case which was proved previously by Millson [Mi]), to the non-arithmetic lattices inSO(n,1) constructed by Gromov and Piatetski-Shapiro [GPS] and to groups generated by reflections.
In the case of 4-dimensional anticommutative algebras a construction is given that links the associated cubic surface and the 27 lines on it with the structure of subalgebras of the algebra.
In the case of 3-dimensional commutative algebras a new proof of a recent theorem of Katsylo and Mikhailov about the 28 bitangents to the associated plane quartic is given.
As in the case of Mumford's geometric invariant theory (which concerns projective good quotients) the problem can be reduced to the case of an action of a torus.
