Series expansions for lattice Green functions
, 2000
"... Lattice Green functions appear in lattice gauge theories, in lattice models of statistical physics and in random walks. Here, space coordinates are treated as parameters and series expansions in the mass are obtained. The singular points in arbitrary dimensions are found. For odd dimensions these ar ..."

CHEBYSHEV SERIES EXPANSION OF INVERSE POLYNOMIALS
, 2005
"... Abstract. An inverse polynomial has a Chebyshev series expansion k∑ 1 / bjTj(x) = anTn(x) j=0 if the polynomial has no roots in [−1,1]. If the inverse polynomial is decomposed into partial fractions, the an are linear combinations of simple functions of the polynomial roots. Also, if the first k of ..."

Univariate Power Series Expansions in Reduce
- Proceedings of ISSAC’90
, 1999
"... We describe the development of a formal power series expansion package for Reduce which takes advantage of Reduce's domain mechanism to make for a seamless integration of series values with the rest of the Reduce system. Consequently, series values may be manipulated with the same algebraic ope ..."

Incomplete series expansion for function approximation
, 2005
"... We present an incomplete series expansion (ISE) as a basis for function approximation. The ISE is expressed in terms of an approximate Hessian matrix which may contain second, third and even higher order ‘main ’ or diagonal terms, but which excludes ‘interaction ’ or off-diagonal terms. From the ISE ..."
