The regularity index of up to 2n−1 equimultiple fat points of P^n
No full textAbstract. Let X = mP_1 + +mP_n+k be a fat point subscheme of P^n, where Supp(X) consists
of n + k distinct points which generate P^n: We study the regularity index tau (X) of X, which is the
least degree in which the Hilbert function of X equals its Hilbert polynomial. We prove that the
generalized Segre's bound for tau (X) holds if n>=4 and there are k+3 points of Supp(X) on a linear 3-dimensional
subspace. We assume Supp(X) is not in general position and call d the least integer for
which there exists a linear subspace of dimension d containing at least d+2 points of Supp(X).
We prove that the generalized Segre's bound holds for simple points when either 3<=k<=n+1
and d>k-3 or k = 4 with no restriction on d. For m greater than or equal to 2 we prove the generalized Segre's bound
when Supp(X) consists of n+4 points and either there are at least 3 points on a line or at least
5 points on a plane or at least 6 points on a linear 3-dimensional subspace. Finally we prove that, in
general, 2m-1<=tau(X) <= 2m when 3<=k<=n-1 and d > k-1; and we extend this result to
the non-equimultiple case. We also provide cases in which the previous bound gives the generalized
Segre's bound

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
