Exponential networks in action and a tt* viewpoint, part II
We will start by a short recapitulation of Gaiotto-Moor-Neitzke's construction of spectral network for theories of class S. We will discuss the Cecotti-Vafa wall crossing in this context. Then we will move to the exponential networks. We will visit the example of framed C^3 (and if the time permits , some aspects of resolved conifold). We will finish by drawing connections with a higher dimensional (3d) tt* system.
