Talcott Parsons science. Parsons also became strongly interested in systems theory and cybernetics and began to adopt their basic ideas and concepts to the realm of social science, especially the work of Norbert Wiener (1894–1964) had his attention. Some of the students who arrived at the Department of Social Relations in the years after the Second World War were David Aberle, Gardner Lindzey, Harold Garfinkel, David G. Hays, Benton Johnson, Marian Johnson, Kaspar Naegele, James Olds, Albert Cohen, Norman Birnbaum, Robin Murphy Williams, Jackson Toby, Robert N. Bellah, Joseph Kahl, Joseph Berger, Morris Zelditch, Renee Fox, Tom O'Dea, Ezra Vogel, Clifford Geertz,
Wiener algebra Wiener algebra In mathematics, the Wiener algebra, named after Norbert Wiener and usually denoted by , is the space of absolutely convergent Fourier series. Here denotes the circle group. The norm of a function is given by where is the th Fourier coefficient of . The Wiener algebra is closed under pointwise multiplication of functions. Indeed, therefore Thus the Wiener algebra is a commutative unitary Banach algebra. Also, is isomorphic to the Banach algebra , with the isomorphism given by the Fourier transform. The sum of an absolutely convergent Fourier series is continuous, so where is the ring of continuous
