Acreage response in Pakistan: a co‐integration approach [PDF]

open access: yesAgricultural Economics, 2002
AbstractThis paper seeks to quantify the acreage responses of wheat, cotton, sugarcane and rice in Pakistan using co‐integration techniques and impulse response analysis. Results indicate that acreages of wheat and basmati rice do not respond significantly to shocks in own‐price while cotton, sugarcane and high yielding variety (HYV) rice do, and that ...

On representation theory of total (co)integrals [PDF]

open access: yesJournal of Algebra and Its Applications, 2016
In this paper, we show that total integrals and cointegrals are new sources of stable anti-Yetter–Drinfeld modules. We explicitly show that how special types of total (co)integrals can be used to provide both (stable) anti Yetter–Drinfeld and Yetter–Drinfeld modules.

Co-Integrable Sets and Probability

open access: yesInternational Journal on Recent Trends in Life Science & Mathematics, 2022
Let us suppose |g| = M. We wish to extend the results of [20] to stochastically Fourier, trivially real, left- totally Atiyah scalars. We show that there exists a right-everywhere stable partially compact point. This leaves open the question of separability. We wish to extend the results of [20] to super-invertible, null planes.

THE SEMINORMED FUZZY CO-INTEGRAL

open access: yesJournal of Korean Institute of Intelligent Systems, 2004
In this paper, we introduce the seminormed fuzzy co-integral as a complementary concept of seminormed fuzzy integral, and investigate its properties. Furthermore we propose an application of this new integral for decision making problems.
