[[Algebra]] ([[Fr]]. ''[[algèbre]]'') is a branch of [[mathematics]] * which reduces the solution of problems to manipulations of [[symbolic]] expressions, and* concerned with the properties and relationships of abstract entities represented in symbolic form.
==Formalization==
In 1955, [[Lacan]] begins to use [[algebraic]] [[symbol]]s -- in an attempt to [[formalize]] [[psychoanalysis]].

==Development of the Symbols==It is important to remember that :Rather than [[being]] [[understood]] in an intuitive way, the [[symbolalgebraic]]s do not always refer to the same concept throughout [[Lacansymbols]]'s work, but are to be used , manipulated and read in various different ways as his work develops. <ref>{{E}} p.313</ref>
Therefore some caution should be exercised when referring to ==List==[[Image:Lacan-algebra.jpg|thumb|right|[[List of algebraic symbols]]]]The [[algebraic]] [[symbol]]s used by [[Lacan]], which appear principally in the following list [[matheme]]s, [[schema l]] and the [[graph of desire]], are [[List of equivalencesAlgebraic Symbols|listed here]], together with their most common [[meaning]].
==Typographic Details==The typographic details and diacritics are extremely important in ''[[Lacan]]ian [[algebra]].The difference between upper- and lower-case [[symbolList of algebraic symbols|Click here]]s, to view the difference between italicised and non-italicised [[symbol]]s, the use List of the apostrophe, the minus [[sign]], and subscripts; all these details play their part in the [[algebraicAlgebraic Symbols]] system.''
For example ==Development==It is important to [[remember]] that the upper-case letters usually [[symbol]]s do not always refer to the same [[symbolicconcept]] throughout [[orderLacan]]'s [[work]], whereas the lower-case letters usually refer but are used in different ways as his work develops. Therefore some caution should be exercised when referring to the [[imaginarylist]] of [[equivalences]]above.
==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.
