چکیده
Compared with complex and lengthy Gauss-Krüger projection series expansions real number expressions, we improve the function representation of projections rewrite them into “multiple Angle form”, “exponential “double form”. The coefficients were expanded in power based on first eccentricity e third flattening n, respectively, truncation difference was analyzed when to different orders obtain simplified practical formulas for each form premise meeting accuracy requirements geodesy. Through numerical analysis, computational efficiency forward inverse solutions is analyzed, which shows superiority above measures, expressions are obtained, a higher more concise form.

New series expansions of the Gauss hypergeometric function
The Gauss hypergeometric function 2F1(a, b, c; z) can be computed by using the power series in powers of z, z/(z − 1), 1 − z, 1/z, 1/(1 − z), (z − 1)/z. With these expansions 2F1(a, b, c; z) is not completely computable for all complex values of z. As pointed out in Gil, et al. [2007, §2.3], the points z = e±iπ/3 are always excluded from the domains of convergence of these expansions. Bühring [...
متن کاملMultidimensional Fast Gauss Transforms by Chebyshev Expansions
A new version of the fast Gauss transform (FGT) is introduced which is based on a truncated Chebyshev series expansion of the Gaussian. Unlike the traditional fast algorithms, the scheme does not subdivide sources and evaluation points into multiple clusters. Instead, the whole problem geometry is treated as a single cluster. Estimates for the error as a function of the dimension d and the expa...
متن کاملGauss Problem for Function Fields
According to a celebrated conjecture of Gauß , there are infinitely many real quadratic fields whose ring of integers is principal. We recall this conjecture in the framework of global fields. If one removes any assumption on the degree, this leads to various related problems for which we give solutions; namely we prove that there are infinite families of principal rings of algebraic functions ...
متن کاملGauss’ hypergeometric function
We give a basic introduction to the properties of Gauss’ hypergeometric functions, with an emphasis on the determination of the monodromy group of the Gaussian hyperegeometric equation. Initially this document started as an informal introduction to Gauss’ hypergeometric functions for those who want to have a quick idea of some main facts on hypergeometric functions. It is the startig of a book ...

Drawing on the boundary theory (Nippert-Eng, 1996a) and the concept of institutional framework according to Piszczek and Berg (2014), we explore in this paper the link between institutional settings and boundary management practices in the case of selfemployed German lawyers. Qualitative empirical results on the basis of 12 interviews reveal that the institutional context in case of self-employ...
