我们将完成关于局部解析代数的元素的阶的研究[IJ,[I2]。设(X,0X)是一个复空间,(0,m)=(x.& %)它在$ &X上的局部代数。对于x=(x^ · · ·,Xm)中收敛幂级数代数C {%}的某个理想f,θ可以表示为0 = C [x] /I.我们定义了f^O的三种阶。代数阶:^(/)= ^(/)"·= sup {/?:/^ T0.] = sup {f的最低非零齐次项的次数:f是f在C(x)中的代表}降阶([ReJ,cf. [S]):y(i):=lim v(i *)/A J->> 00
We will complete the study [IJ, [I2] on orders of elements of a local analytic algebra. Let (X, 0X) be a complex space and ( 0 , m ) =( ® x.& %) its local algebra at $ &X. (9 can be expressed as 0 = C [x] /I for some ideal / of the algebra C {%} of convergent power series in x= (x^ • • • , Xm). We define three kinds of orders for f^O. algebraic order: ^ (/)= ^ (/)"•= sup {/?: /^ T0.] = sup {the degree of the lowest non-zero homogeneous term of /: / is a representative of f in C(x}} reduced order ([ReJ, cf. [S]): y(/):=lim v(/*)/A J-»oo
