Adams operation
In mathematics, an Adams operation, denoted ψ for natural numbers "k", is a cohomology operation in topological K-theory, or any allied operation in algebraic K-theory or other types of algebraic construction, defined on a pattern introduced by Frank Adams. The basic idea is to implement some fundamental identities in symmetric function theory, at the level of vector bundles or other representing object in more abstract theories.
Adams operations can be defined more generally in any λ-ring over the rational numbers
permanent checkpoints and barricades. These 'no-go areas', however, were re-taken by the British Army in response to the Bloody Friday bombings of 1972, in a major operation named Operation Motorman. The British Army proceeded to build fortified posts in republican west Belfast, thus hampering the IRA's freedom of movement. After this setback, Seamus Twomey, who had authorised the Bloody Friday operation, was replaced as Belfast Brigade commander by Gerry Adams, with Ivor Bell as his second-in-command. Adams
