P−ferrer Diagram, P−linear Ideals and Arithmetical Rank
In this paper we introduce p−Ferrer diagram, note that 1− Ferrer diagram are the usual Ferrer diagrams or Ferrer board, and corresponds to planar partitions. To any p−Ferrer diagram we associate a p−Ferrer ideal. We prove that p−Ferrer ideal have Castelnuovo mumford regularity p + 1. We also study Betti numbers , minimal resolutions of p−Ferrer ideals. Every p−Ferrer ideal is p−joined ideals in...
متن کاملLinear Inequalities for Rank 3 Geometric Lattices
The flag Whitney numbers (also referred to as the flag f -numbers) of a geometric lattice count the number of chains of the lattice with elements having specified ranks. We give a collection of inequalities which imply all the linear inequalities satisfied by the flag Whitney numbers of rank 3 geometric lattices. We further describe the smallest closed convex set containing the flag Whitney num...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولLinear Rank Regression
The errors ei in (1.1) are assumed to be independent and identically distributed, but are not necessarily normal and may be heavy-tailed. Assume for convenience that β is one dimensional. Then (1.1) is a simple linear regression. However, most of the following extends more-or-less easily to higher-dimensional β, in which case (1.1) is a multiple regression. Given β, define Ri(β) as the rank (or...
