To every complex 3-dimensional Calabi-Yau variety $X$ are associated two similar but differing types of sigma-model $N=2$-supersymmetric 2d CFTs. There is at least for some CY $X$ a map $X \mapsto \hat X$ which exchanges the Hodge numbers $h^{1,1}$ and $h^{1,2}$ such that $SCFT_A(X)$ is expected to be equivalent to $SCFT_B(\hat X)$.
This is called mirror symmetry. At least in some cases this can be understood as a special case of T-duality (Strominger-Yau-Zaslow 96).
In this form mirror symmetry remains a conjecture, not the least because for the moment there is no complete construction of these SCFTs. But to every such $SCFT(X)$ one can associate two TCFTs, $A(X)$ and $B(X)$, the A-model and the B-model. These $N=1$ supersymmetric field theories were obtained by Edward Witten using a “topological twist”. The topological A-model can be expressed in terms of symplectic geometry of a variety and the topological B-model can be expressed in terms of the algebraic geometry of a variety.
These topological theories are easier to understand and do retain a little bit of the information encoded in the full SCFTs. In terms of these the statement of mirror symmetry says that passing to mirror CYs exchanges the A-model with the $B$-model and conversely:
By a version of the cobordism hypothesis-theorem, these TCFTs (see there) are encoded by A-∞ categories that are Calabi-Yau categories: the A-model by the Fukaya category $Fuk(X)$ of $X$ which can be understood as a stable (∞,1)-category representing the Lagrangian intersection theory on the underlying symplectic manifold; and the B-model by an enhancement of the derived category of coherent sheaves $D^b_\infty(\hat X)$ on $\hat X$.
In terms of this data, mirror symmetry is the assertion that these A-∞ categories are equivalent and simultaneously the same under exchange $X\leftrightarrow \hat{X}$:
This categorical formulation was introduced by Maxim Kontsevich in 1994 under the name homological mirror symmetry. The equivalence of the categorical expression of mirror symmetry to the SCFT formulation has been proven by Maxim Kontsevich and independently by Kevin Costello, who showed how the datum of a topological conformal field theory is equivalent to the datum of a Calabi-Yau A-∞-category(see TCFT).
The mirror symmetry conjecture roughly claims that every Calabi-Yau 3-fold has a mirror. In fact one considers (mirror symmetry for) degenerating families for Calabi-Yau 3-folds in large volume limit (which may be expressed precisely via the Gromov-Hausdorff metric). The appropriate definition of (an appropriate version of) the Fukaya category of a symplectic manifold is difficult to achieve in desired generality. Invariants/tools of Fukaya category include symplectic Floer homology and Gromov-Witten invariants (building up the quantum cohomology).
Mirror symmetry is related to the T-duality on each fiber of an associated Lagrangian fibration Strominger-Yau-Zaslow 96.
Although the non-Calabi-Yau case may be of lesser interest to physics, one can still formulate some mirror symmetry statements for, for instance, Fano manifolds. The mirror to a Fano manifold is a Landau-Ginzburg model (see Hori-Vafa 00; see also work of Auroux for an explanation via the Strominger-Yau-Zaslow T-duality philosophy). Then the statements are: the A-model of the Fano (given by the Fukaya category) is equivalent to the B-model of the Landau-Ginzburg model (given by the category of matrix factorizations); and the B-model of the Fano (given by the derived category of sheaves) is equivalent to the A-model of the Landau-Ginzburg model (given by the Fukaya-Seidel category). A few of the relevant names: Kontsevich, Hori-Vafa, Auroux, Katzarkov, Orlov, Seidel, …
