	In [[mathematics]] and [[string theory]], a '''conifold''' is a generalization of a [[manifold]]. Unlike manifolds, conifolds can contain [[gravitational singularity#Conical\|conical singularities]], i.e. points whose neighbourhoods look like [[cone (geometry)\|cones]] over a certain base. In [[physics]], in particular in [[Compactification (physics)#Flux compactification\|flux compactification]]s of [[string theory]], the base is usually a five-[[dimension]]al real manifold, since the typically considered conifolds are complex 3-dimensional (real 6-dimensional) spaces.

	Conifolds are important objects in [[string theory]]: [[Brian Greene]] explains the [[physics]] of conifolds in Chapter 13 of his book ''The Elegant Universe'' - including the fact that the space can tear near the cone, and its [[topology]] can change. This possibility was first noticed by {{harvtxt\|Candelas\|Dale\|Lutken\|Schimmrigk\|1988}} and employed by {{harvtxt\|Green\|Hübsch\|1988}} to prove that conifolds provide a connection between all (then) known Calabi-Yau compactifications in string theory; this partially supports a conjecture by {{harvtxt\|Reid\|1987}} whereby conifolds connect all possible Calabi-Yau complex 3-dimensional spaces.

			A well-known example of a conifold is obtained as a deformation limit of a quintic - i.e. a [[quintic hypersurface]] in the [[complex projective plane\|projective space]] <math>\mathbb{CP}^4</math>. The space <math>\mathbb{CP}^4</math> has complex dimension equal to four, and therefore the space defined by the quintic (degree five) equations

If the [[complex structure]]{{dn\|date=September 2012}} [[parameter]] <math>\psi</math> is chosen to become equal to one, the manifold described above becomes singular since the [[derivative]]s of the quintic [[polynomial]] in the equation vanish when all coordinates <math>z_i</math> are equal or their [[ratio]]s are certain fifth roots of unity.

			In the context of [[string theory]], the geometrically singular conifolds can be shown to lead to completely smooth physics of strings. The divergences are "smeared out" by [[D-branes\|D3-branes]] wrapped on the shrinking three-sphere in [[Type IIB string theory]] and by [[D-branes\|D2-branes]] wrapped on the shrinking two-sphere in [[Type IIA string theory]], as originally pointed out by {{harvtxt\|Strominger\|1995}}.

	:<~~math~~>~~z_1^5+z_2^5+z_3^5+z_4^5+z_5^5-5\psi z_1z_2z_3z_4z_5 = 0~~<~~/math~~>

	~~in terms~~ of ~~homogeneous coordinates <math>z_i</math> on <math>\mathbb{CP}^4</math>~~, for ~~any fixed complex~~ <~~math~~>~~\psi~~<~~/math~~>, ~~has complex dimension three. This family~~ of ~~[[quintic hypersurface]]s~~ is ~~the most famous example of [[Calabi-Yau manifold]]s~~. ~~If the [[complex structure]]{{dn\|date=September 2012}} [[parameter]] <math>\psi</math> is chosen~~ to ~~become equal~~ to one, ~~the manifold described above becomes singular since the [[derivative]]s~~ of ~~the quintic [[polynomial]] in the equation vanish when all coordinates~~ <~~math~~>~~z_i~~<~~/math~~> ~~are equal or their [[ratio]]s are certain fifth roots of unity~~. ~~The neighbourhood of this singular point looks like~~ a ~~[[cone (geometry)\|cone]] whose base is [[topology\|topologically]] just~~ <~~math~~>~~S^2 \times S^3~~<~~/math~~>.

	In the ~~context of [[string theory]]~~, ~~the geometrically singular conifolds can be shown to lead to completely smooth physics~~ of ~~strings~~. ~~The divergences~~ are ~~"smeared out" by [[D-branes\|D3-branes]] wrapped on the shrinking~~ three~~-sphere~~ in ~~[[Type IIB string theory]]~~ and ~~by [[D-branes\|D2-branes]] wrapped on the shrinking two-sphere in [[Type IIA string theory]], as originally pointed out by {{harvtxt\|Strominger\|1995}}~~. ~~As shown by {{harvtxt\|Greene\|Morrison\|Strominger\|1995}}, this provides the string-theoretic description~~ of ~~the [[topology]]-change via the conifold transition originally described by {{harvtxt\|Candelas\|Green\|Hübsch\|1990}}~~, ~~who also invented the term "conifold" and the diagram~~
	~~:[[Image:3FoldConifoldTransition~~.~~pdf\|600px]]~~
	~~for the purpose. The two topologically distinct ways~~ of smoothing a conifold are thus shown to involve replacing the singular vertex (node) by either a 3-sphere (by way of deforming the complex structure) or a 2-sphere (by way of a "small resolution"). It is believed that nearly all [[Calabi-Yau]] manifolds can be connected via these "critical transitions", ~~resonating with Reid~~'s ~~conjecture.~~
