Geometry of Whitney-type Formulas
نویسنده
چکیده
The article contains a generalization of the classical Whitney formula for the number of double points of a plane curve. This formula is split into a series of equalities, and also extended to curves on a torus, to non-pointed curves, and to wave fronts. All the theorems are given geometric proofs employing logarithmic Gauss-type maps from suitable configuration spaces to C. 2000 Math. Subj. Class. Primary 57M25, 57N35.

Kinematic Formulas for Finite Lattices
In analogy to valuation characterizations and kinematic formulas of convex geometry, we develop a combinatorial theory of invariant valuations and kinematic formulas for finite lattices. Combinatorial kinematic formulas are shown to have application to some probabilistic questions, leading in turn to polynomial identities for Möbius functions and Whitney numbers.
متن کاملGenerating Kummer Type Formulas for Hypergeometric Functions
Kummer type formulas are identities of hypergeometric series. A symmetry by the permutations of n-letters yields these formulas. We will present an algorithmic method to derive known and new Kummer type formulas. The algorithm utilizes several algorithms in algebra and geometry for generating Kummer type formulas.
متن کاملOn Whitney numbers of the order ideals of generalized fences and crowns
We solve some recurrences given by E. Munarini and N. Zagaglia Salvi proving explicit closed formulas for Whitney numbers of the distributive lattices of order ideals of the fence poset and crown poset. Moreover, we get explicit closed formulas for Whitney numbers of lattices of order ideals of fences with higher asymmetric peaks.
متن کاملA general type of twisted anomaly cancellation formulas
For even dimensional manifolds, we prove some twisted anomaly cancellation formulas which generalize some well-known cancellation formulas. For odd dimensional manifolds, we obtain some modularly invariant characteristic forms by the Chern-Simons transgression and we also get some twisted anomaly cancellation formulas. Subj.

متن کاملSpecial Finite Elements for Dipole Modelling
This thesis focuses on the solution of the EEG forward problem, using the finite element method. The goal is to compare different dipole models for a current source in the human head, with a focus on Whitney type basis functions. For the current sources in the head a widely used model is the mathematical or current dipole. Its strong singularity poses a problem for numerical methods. Therefore ...
