An Alternate Construction of the Berlekamp Subalgebra

  • Greg Stein
Conference paper


We give an alternate construction of the Berlekamp subalgebra for cyclotomic polynomials over finite fields. This gives a new, deterministic, polynomial time reduction of factoring these polynomials to knowing the trace of an appropriate root of unity.
