In the context of measure-theoretic probability, which property must a collection of subsets $\backslash mathcal\{F\}$ of a sample space $\backslash Omega$ satisfy to be considered a $\backslash sigma$-algebra?

If a sequence of random variables $X\_\{n\}$ converges to $X$ in $L^\{p\}$ norm for some $p\; \backslash geq\; 1$, then it necessarily converges to $X$ almost surely.

In the context of a probability space $(\backslash Omega,\; \backslash mathcal\{F\},\; P)$, what is the term for a sub-sigma-algebra $\backslash mathcal\{G\}\; \backslash subseteq\; \backslash mathcal\{F\}$ that represents the information available at a specific time in a stochastic process?

Unscramble the letters to identify the property of a sequence of random variables $X\_\{n\}$ that converges to a constant $c$ such that for every $\backslash epsilon\; >\; 0$, $P(|X\_\{n\}\; -\; c|\; >\; \backslash epsilon)\; \backslash to\; 0$ as $n\; \backslash to\; \backslash infty$.

Before we proceed to the advanced study of Change of Measure (CXZ), we must ensure a solid grasp of Radon-Nikodym derivatives and Martingale properties. Which of the following statements correctly describe the properties of a probability measure $Q$ that is equivalent to a measure $P$ on a measurable space $(\backslash Omega,\; \backslash mathcal\{F\})$?
