Galoisian approach to complex oscillation theory of some Hill equations
Yik-Man Chiang, Guo-Fu Yu
We apply Kovacic's algorithm from differential Galois theory to show that all complex non-oscillatory solutions (finite exponential of convergence of zeros) of certain Hill equatio…

Supersymmetry of the quantum rotor
Vincent X. Genest, Luc Vinet, Guo-Fu Yu +1
The quantum rotor is shown to be supersymmetric. The supercharge , whose square equals the Hamiltonian, is constructed with reflection operators. The conserved quantities that c…
