An orbitope is the convex hull of an orbit of a compact group acting linearly on a vector space. Instances of these highly symmetric conex bodies have appeared in many areas of mathematics and its applications, including protein reconstruction, symplectic geometry, and calibrations in differential geometry. In this talk, I will discuss Orbitopes from the perpectives of classical convexity, algebraic geometry, and optimization with an emphasis on ten motivating problems and concrete examples. This is joint work with Raman Sanyal and Bernd Sturmfels.
