Stable and upgraded horizontal datum for India

Chart Datum for Hydrography

This paper sets out to discuss ongoing activities in the tide and chart datum components of hydrography and charting. It expands on the paper presented at FIG (Fédération Internationale des Géomètres) in Brighton 1998 by Mr Matt Higgins and is a revised and updated version of the paper Chart Datum for Hydrography by GPS delivered by the present authors to the Survey 99 Congress, Sunshine Coast,...

Horizontal and Vertical Inequalities in India

Using the first nationally representative detailed income data for India from the 2005 India Human Development Survey (IHDS), Desai and colleagues (2010) reported Indian income inequality to have the high levels typical for lowand middle-income countries. The IHDS Gini of 0.52 puts India at a similar level as Brazil (0.49) and well above the levels observed even in the most unequal high-income ...

Stable Market Structure and Sufficient Conditions for Horizontal Mergers

Consider the four possible mergers in a market with three firms: 12, 13, 23, and 123. Which one, if any, will take place? Although the question seems fairly simple, it has not yet been fully answered. The existing literature provides two necessary conditions for a merger: profitability and a non-empty core (i.e., a merger will not be formed if it is unprofitable or if its core is empty). This p...

Upgraded methods for the effective computation of marked schemes on a strongly stable ideal

Let J ⊂ S = K[x0, . . . , xn] be a monomial strongly stable ideal. The collection Mf(J) of the homogeneous polynomial ideals I, such that the monomials outside J form a K-vector basis of S/I, is called a J-marked family. It can be endowed with a structure of affine scheme, called a J-marked scheme. For special ideals J , J-marked schemes provide an open cover of the Hilbert scheme Hilbnp(t), wh...
