{{Top}}[[Topology]] (''topologie'') is a branch of [[mathematics]] which deals with the properties of figures in space which are preserved under all continuous deformations.These properties are those of continuity, contiguity and delimitation. The notion of space in topology is one of topological space, which is not limited to Euclidean (two- and three-dimensional space), nor even to spaces which can be said to have a dimension at all. Topological space thus dispenses with all references to distance, size, area and angle, and is based only on a concept of closeness or neighbourhood.{{Bottom}}
=====Sigmund Freud=====
/* In what have been called his two "[[topology|topographies]]" (the first dating from 1900 and the second from 1923), [[Freud]] resorted to [[schema]]s to [[represent]] the various parts of the [[psychic apparatus]] and their interrelations. These schemas implicitly posited an equivalence between [[psychic]] space and Euclidean space. */
=====Figures=====
While [[schema L]] and the other [[schemata]] which are produced in the 1950s can be seen as [[Lacan]]'s first incursion into [[topology]], topological forms only come into prominence when, in the 1960s, he turns his attention to the figures of the [[torus]], the [[moebius strip]], [[Klein]]'s bottle, and the [[cross-cap]].<ref>{{L}} ''[[Works of Jacques Lacan|Le Séminaire. Livre IX. L'identification, 1961-62]]'', unpublished.</ref> Later on, in the 1970s, [[Lacan]] turns his attention to the more [[complex]] area of [[knot]] [[theory]], especially the [[Borromean knot]].
