Brick Generation
A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. The importance of bricks stems from the fact that they are building blocks of the matching decomposition procedure of Kotzig, and Lovász and Plummer. We prove that every brick except for the Petersen graph can be reduced to K4 or the prism by repeatedly applying a ce...
متن کاملStarting from scratch and building brick by brick in comprehension.
During narrative comprehension, readers construct representations of the situation described by a text, called situation models. Theories of situation model construction and event comprehension posit two distinct types of situation model updating: incremental updating of individual situational dimensions, and global updates in which an old model is abandoned and a new one created. No research t...
متن کاملBrick Manifolds and Toric Varieties of Brick Polytopes
In type A, Bott-Samelson varieties are posets in which ascending chains are flags of vector spaces. They come equipped with a map into the flag variety G/B. These varieties are mostly studied in the case in which the map into G/B is birational to the image. In this paper we study Bott-Samelsons for general types, more precisely, we study the combinatorics a fiber of the map into G/B when it is ...
متن کاملBrick partitions of graphs
For each rational number q ≥ 1, we describe two partitions of the vertex set of a graph G, called the q-brick partition and the q-superbrick partition. The special cases when q = 1 are the partitions given by the connected components and the 2-edge-connected components of G, respectively. We obtain structural results on these partitions and describe their relationship to the principal partition...
