so 1+ω +ω ^2+ω ^3= (1(1-ω ^4))(1-ω )= (1-ω ^4)(1-ω )= (1-1)(1-ω )=0 as required Since S_n= (a(1-r^n))(1-r) for a geometric series.Since ω ^4=1, as ω is a complex 4th root of unity.反馈 收藏 ...

Firstly, observe that in a field of finite characteristicp, every element that is algebraic (i.e. is the solution to some polynomial with coefficients in the ring generated by 1) is an element of some finite subfield, and is therefore a root of unity. As such, in our putative field of...
'az + b' is the group of affine transformations of complex plane . The coefficients a, . In quantum version a, b are normal operators such that ab = q2ba, where q is the deformation parameter. We shall assume that q is a root of unity, more precisely , where N is an even natural...
