We consider dimensionally reduced versions ofN = 2 four–dimensional supersymmetric Yang-Mills theory and determine the one-loop effective Lagrangians associated with the motion over the corresponding moduli spaces. In the (0 + 1) case, the effective Lagrangian describes an N = 4 supesymmetric quantum mechanics of the Diaconescu– Entin type. In (1+ 1) dimensions, the effective Lagrangian represe...

We study the finite-size corrections of the dimer model on∞×N square lattice with two different boundary conditions: free and periodic. We find that the finite-size corrections depend in a crucial way on the parity of N , and show that, because of certain non-local features present in the model, a change of parity ofN induces a change of boundary condition. Taking a careful account of this, the...
