Flag-Accurate Arrangements [PDF]
In [MR21], the first two authors introduced the notion of an accurate arrangement, a particular notion of freeness. In this paper, we consider a special subclass, where the property of accuracy stems from a flag of flats in the intersection lattice of ...

SelMa - Self-guided Learning in Teaching Mathematics
In the project ``Self-guided Learning in Teaching Mathematics - SEC II'' (SelMa), five authoring schools are working out scenarios, media and materials for phases of self-guided learning, which will be tested systematically by 10 trial schools with ...

Hyperfactored of Reflection Arrangement A�(G_25 ) [PDF]
The purpose of this paper is to study the hyperfactored of the complex reflection arrangementA(G 25 ). Depending on the lattice of arrangement A(G 25 ), the basis of A(G 25 ) has been foundand then partitioned. Also, showed that A(G 25 ) is not hyperfactored and is not inductivelyfactored.

Restricting Invariants and Arrangements of Finite Complex Reflection Groups [PDF]
Suppose that G is a finite, unitary reflection group acting on a complex vector space V and X is a subspace of V. Define N to be the setwise stabilizer of X in G, Z to be the pointwise stabilizer, and C=N/Z.

Some Almost Exceptional Arrangements [PDF]
We introduce and study a family of real hyperplane arrangements that includes the reflection arrangements of types A and D as well as an infinite family of arrangements E′n (constructed by Orlik, Solomon, and Terao) related to the exceptional ...

Euclidean matchings and minimality of hyperplane arrangements [PDF]
We construct a new class of maximal acyclic matchings on the Salvetti complex of a locally finite hyperplane arrangement. Using discrete Morse theory, we then obtain an explicit proof of the minimality of the complement.

Modular Equalities for Complex Reflection Arrangements
We compute the combinatorial Aomoto-Betti numbers \beta_{p}(\mathcal A) of a complex reflection arrangement. When \mathcal A has rank at least 3, we find that

Measuring the Reflection Matrix of a Rough Surface
Phase modulation methods for imaging around corners with reflectively scattered light required illumination of the occluded scene with a light source either in the scene or with direct line of sight to the scene. The RM (reflection matrix) allows control
