Toupin, Daniel: Location, Multiplicity, and Exclusion: Three Spectral Forms of three Millennium Problems in the Shadow Framework

This paper isolates a common spectral grammar behind three Millennium Problems which, in their classical formulations, appear to belong to different worlds. Each problem is associated with a shadow-symmetric spectral datum: a Hilbert space, an involution exchanging two spectral half-planes, and a fixed self-dual interface. For the Riemann zeta-function the interface is the critical line Re(s) = 1/2; for an elliptic L-function the interface is the central point s = 1; for Yang-Mills the interface
