A method for fast and highly accurate evaluation of the generalized hypergeometric function p F p−1(a 1, ..., a p ; b 1, ..., b p−1; 1) = Σ k = 0 ∞ f k by means of the Hurwitz zeta function ζ(α, s) is developed. Based on asymptotic analysis of the coefficients f k , an expansion of p F p−1 is constructed as a combination of the functions ζ(α, s) with… (More)

Various quadrature formulas are classified among the classical integration methods. New quadratures designed for a wide spectrum of problems from various fields of natural sciences have been rapidly developing during last decades [1]. For example, in some problems of elementary particle physics and elasticity theory, it is required to evaluate singular and… (More)

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… (More)
