Abstract: In this talk I will review a generalization of the spectral networks, known as exponential networks, which produce enumerative invariants associated to special Lagrangians in certain Calabi-Yau threefolds. Applications will include the computation of the exact spectrum for the mirror of the local Hirzebruch surface. There will also be a sketch of a new derivation of this framework, which elucidates the geometric meaning of the invariants in terms of elementary data of A-branes. (Based on joint works with P. Longhi and M.Romo.)
