Query: Quantum superconductor-metal transition in a proximity array   A theory of the zero-temperature superconductor-metal transition is developed
for an array of superconductive islands (of size d) coupled via a disordered
two-dimensional conductor with the dimensionless conductance g>>1. At T=0
macroscopically superconductive state of the array with the lattice spacing
b>>d is destroyed at g < g_c \approx 0.1 ln^2(b/d). At high temperatures the
normal-state resistance between neighboring islands at b=b_c is much smaller
than h/4e^2.
