Dihedral bi-invariant cohomology
Dihedral bi-invariant cohomologies of two algebras with involutions over the ring \(k\) are introduced. The author determines the bi-invariant cohomologies with symmetries which generalize cyclic, quaternion and dihedral bi-invariant cohomologies. The case when \(1/2\in k\) is analysed separately.
