We investigate the existence and properties of solutions to a second-order singular ODE. We base ourselves on the variational approach, which enables the approximation of solutions and gives a measure of a duality gap between primal and dual functional for minimizing sequences.
The bound states of p holes are studied within the two-dimensional two-band model with the antiferromagnetic exchange interaction between d and p spins, J. The binding energies of p holes are computed as a function of the Cu-O transfer and one of J within the mean-field theory with the periodic boun
