摘要：

An efficient analytic-numerical method for finding soliton solutions in the gauge-invariant Heisenberg antiferromagnet model is suggested. The method is based on power and asymptotic series and on the analytic continuation technique: re-expansions and Pade approximants. Symbolic evaluations are used both for constructing the series and for efficient finding initial approximations to the solutions.
