Algorithmic approach for Formal Fourier Series

open access: yes, 2020
. The study of trigonometric series has started at the beginning of the nineteenth century. Joseph Fourier made the important observation that almost every function of a closed interval can be decomposed into the sum of sine and cosine functions.

Exceptional sets and fiber products

open access: yes, 2007
Exceptional sets where fibers have dimensions higher than the generic fiber dimension are of interest in mathematics and in application areas, such as the theory of overconstrained mechanisms.

Algebraic Expressions for Directed Grid Graphs with Diagonal Edges: Decomposition Bounds, Lower Bounds, and Algebraic-Branching-Program Methods

open access: yes
We study formal path expressions for two edge-labeled two-terminal directed acyclic graph families: directed triangulated grid graphs (TGGs) and directed king graphs.

Generation of invariants in theorema

open access: yes, 2003
. Explicitly stated program invariants can help programmers by identifying program properties that must be preserved when modifying code. In practice, in most of the cases, however, these invariants are usually implicit.

Solving Polynomial Systems Equation by Equation

open access: yes, 2007
By a numerical continuation method called a diagonal homotopy, one can compute the intersection of two irreducible positive dimensional solution sets of polynomial systems.

Applications of a Numerical Version of Terracini's Lemma for Secants and Joins

open access: yes, 2006
This paper illustrates how methods such as homotopy continuation and monodromy, when combined with a numerical version of Terracini's lemma, can be used to produce a high probability algorithm for computing the dimensions of secant and join ...
