Phys. Rev. E 64, 066106 (2001) [4 pages]Simplifying Kaufman’s solution of the two-dimensional Ising modelReceived 25 April 2001; revised 2 August 2001; published 13 November 2001 We considerably simplify Kaufman’s solution of the two-dimensional Ising model by introducing two commuting representations of the complex rotation group SO(2n,C). All eigenvalues of the transfer matrix and therefore the partition function are found in a straightforward way. © 2001 The American Physical Society URL:
