$\sigma$-Localization and $\sigma$-Martingales [PDF]

open access: yesTheory of Probability & Its Applications, 2004
The concept of \(\sigma\)-localization, which is a generalization of localization in the general theory of stochastic processes, is introduced. \(\sigma\)-martingales are obtained from the class of martingales by a \(\sigma\)-localization procedure. They can be interpreted naturally as semimartingales with vanishing drift and play a key role in the ...

open access: yesAAOHN Journal, 2010
When I was first introduced to the Six Sigma process, I resisted it with every ounce of energy I had. I continuously fabricated reasons so that I was unable to complete the training that my company required. When it came time for my performance review, I could not hide the truth from my manager; I had not completed the required training.

\Sigma-convergence

open access: yesBanach Journal of Mathematical Analysis, 2011
The usual approach to the weak convergence of a product of functions is to require one of the sequences to converge strongly. For example, if \(u_n \to u\) in \(L^p(\Omega)\), \(v_n \rightharpoonup v\) in \(L^{p^{\prime}}(\Omega)\), then \(u_n v_n \rightharpoonup uv\) in \(L^1(\Omega)\), where \(\rightharpoonup\) means weak convergence.
