摘要:

对于关于2的第二类域$K$,考虑了在$K$上将二项式$x^{2^n} - a$分解为不可约因子的乘积,并求出了$K$上循环2-群$<g>$的扭群代数$K^t< g>$的极小幂等元的显式.

英文摘要:

For a field $K$ of the second kind with respect to 2 and of characteristic different from 2, we consider the decomposition of the binomials $x^{2^n} - a$ into a product of irreducible factors over $K$ and find the explicit form of the minimal idempotents of the twisted group algebra $K^t< g>$ of a cyclic 2-group $<g>$ over $K$.
