✦ Synopsis

This paper presents two efficient computational techniques in algebraic geometry. The first one allows the elimination of redundancies in the representation of quasi-projective varieties by atlases of affine charts. The second simplifies the computations with exponentiated ideals by attaching rational weights to the generators, applying Hironaka's theory of idealistic exponents. As the main application, we used these techniques to speed up Villamayor's algorithm for resolving hypersurface singularities in any dimension.

## Abstract An effective technique for extracting the singularity of plane wave spectra in the computation of antenna aperture fields is proposed. The singular spectrum is first factorized into a product of a finite function and a singular function. The finite function is inverse Fourier transforme

## Abstract We deal here with colorings of the pair (__μ__^+^, __μ__), when __μ__ is a strong limit and singular cardinal. We show that there exists a coloring __c__ with no refinement. It follows that the properties of colorings of (__μ__^+^, __μ__) when __μ__ is singular differ in an essential wa

A standard boundary element method discretization for the electromagnetic compatibility problem is analysed, revealing the near-singularity of the dense linear system for the lower frequency range. Next, a new basis transformation is presented, that separates the dominating capacitive effects from t

We present geometric design techniques for observer design in generalized state-space or singular systems. The unknown-input-conditioned invariant subspaces are defined for singular systems, and are related to the solution of a generalized Lyapunov equation. The approach emphasizes solution procedur
