An extension of certain quasi-measure

An Extension of Enhanced Russell Measure to deal with Interval Scale Data in DEA

Data Envelopment Analysis (DEA) models with interval inputs and outputs have been rarely discussed in DEA literature. This paper, using the enhanced Russell measurement proposes an extended model which permits the presence of interval scale variables which can take both negative and positive values. The model is compared with most well-known DEA models of which include the CCR model, the BCC mo...

An extension of stochastic calculus to certain non-Markovian processes

By time changes of Lévy processes we construct two operators on Fock space whose sum is a second quantized operator, and that complement the annihilation and creation operators whose probabilistic interpretations use shifts of trajectories. This results in an analytic construction, for certain nonMarkovian processes, of stochastic calculus including Itô differentials, generators and associated ...

An Extension Theory for a Certain Class of Loops

Introduction. If £ is a group with a normal subgroup K one may form the quotient group E/K^M. Conversely, for preassigned groups K, M, there is the extension problem: to determine (in some sense) all groups E with K as normal subgroup such that E/K^M. Much progress has been made on this problem, particularly through the work of Baer [l, 2, 3] and the cohomology theory of Eilenberg and MacLane [...
