[[Algebra]] ([[Fr]]. ''[[algèbre]]'') is a branch of [[mathematics]] -- or which reduces the solution of problems to manipulations of [[logicsymbolic]] -- concerned with the properties and relationships of abstract entities represented in symbolic formexpressions.
==Jacques LacanFormalization==In 1955, [[Jacques Lacan]] begins to use [[algebraic]] [[symbol]]s in 1955 -- in an attempt to [[formaliseformalize]] [[psychoanalysis]]. ===Formalization of Psychoanalysis===
Three main reasons lie behind this attempt at [[formalization]].
:Rather than being understood in an intuitive way, the [[algebraic]] [[symbols]] are to be used, manipulated and read in various different ways.<ref>{{E}} p.313</ref>
==List of Algebraic Symbols==[[Image:Lacan-algebra.jpg|thumb|right|[[List of algebraic symbols]]]]The [[algebraic]] [[symbol]]s used by [[Lacan]] , which appear principally in the [[matheme]]s, [[schema l]] and the [[graph of desire]], are [[List of Algebraic Symbols|listed here]], together with their most common [[meaning]].
==Details==
The typographic details and diacritics are extremely important in [[Lacan]]ian [[algebra]].
The difference between upper- and lower-case [[symbol]]s, the difference between italicised and non-italicised [[symbol]]s, the use of the apostrophe, the minus [[sign]], and subscripts; all these details play their part in the [[algebraic]] system. For example the upper-case letters usually refer to the [[symbolic]] [[order]], whereas the lower-case letters usually refer to the [[imaginary]]. The use of the [[bar]] is also important.
