A partial differential approximant (or PDA), F ( x, y ) approximates a function f ( x, y ), specified by its truncated power series, in terms of a solution of a defining linear partial differential equation with polynomial coefficients. The intrinsic multisingularities of a PDA, which may approximate corresponding singularities of f ( x, y ), are analysed formally and shown to obey, in general, asymptotic scaling (as familiar in the theory of critical phenomena), i. e. F ( x, y ) ≈ C | x͠ | - γ Z ( y͠ /| x͠ | ϕ ) + B , where x͠ and y͠ are linear combinations of the deviations, ( x - x c ) and ( y - y c ), from the multisingular point ( x c , y c ). Explicit formulae, suitable for numerical computation, are derived for the characteristic exponents, γ and ϕ , for the scaling function Z ( • ), for its expansion coefficients and for the related coefficients C and B , in the case when the crossover exponent, ϕ , lies in the interval (½, 2). (Part II extends these results to general values of ϕ , which requires the introduction of the nonlinear scaling fields associated with the PDA.)
