Visible L - Theory

چکیده
The visible symmetric L-groups are a refinement of the symmetric L-groups of Mishchenko [12] and Ranicki [15]. They are much easier to compute, although they hardly differ from the symmetric L-groups in their formal properties. Cappell and Shaneson [3] use the visible symmetric L-groups in studying 4-dimensional s-cobordisms; see also Kwasik and Schultz [8]. The visible symmetric L-groups are related to the Ronnie Lee L-groups of Milgram [11].

متن کاملThe Visible: Element of the Social
In the context of a social-theoretical take on the link between social life and visibility, this paper invites to shift the focus from visibility phenomena to “the visible”. A theory of visibility, it is submitted, must be constructed as a theory of the medium. In opposition to visibility as a set of formal relations, what the visible brings to the fore is the existence of a mid-term, a connect...
