This workshop, sponsored by AIM and the NSF, will be devoted to problems in calibrated geometry related to mirror symmetry and gauge theory.

Mirror symmetry provides a correspondence between the symplectic geometry of one Calabi-Yau manifold and the complex geomery of its mirror partner. A typical example is the correspondence between the combinatorial problem of counting the number of holomorphic curves to the theory of variation of Hodge structures.

One of the most important conjectures in Mirror symmetry is the
SYZ conjecture of Strominger, Yau and Zaskow. The conjecture
asserts that the mirror of a Calabi-Yau manifold *X*
can be
obtained by dualizing the fibers of a special Lagrangian toric
fibration of *X*. The conjecture was partially
motivated by the
work of McLean on the moduli space of special Lagrangian cycles.
Similar conjectures were formulated by Leung for manifolds with
exceptional holonomy using other types of calibrated cycles.

The well-developed theory of pseudo-holomorphic curves in almost complex manifolds provides a guide to the sort of results one would like to generalize to calibrated cycles in Riemannian manifolds. Such results would be very useful in higher dimensional geometry. For example, applications of calibrations to gauge theory were proposed by Donaldson and Thomas for Calabi-Yau 3-folds and 4-folds. A unified approach to higher dimensional gauge theory for Riemannian manifolds of any dimension was proposed by Tian using a codimension 4 calibration. A connection of calibrations with Seiberg-Witten equations was found by Akbulut and Salur.

The main goals of the workshop are to clarify the connections between the aforementioned fields, and to identify some target results for both the short and long term. Some specific topics to be discussed include:

- Calibrated cycles and mirror symmetry
- Calibrated geometry and gauge Theory
- Moduli spaces of calibrated cycles

The workshop will differ from typical conferences in some regards. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and parallel working sessions.

The deadline to apply for support to participate in this workshop has passed.
