test for definiteness
1Second partial derivative test — In mathematics, the second partial derivatives test is a method in multivariable calculus used to determine if a critical point ( x , y ) is a minimum, maximum or saddle point.Suppose that :M = f {xx}(a,b)f {yy}(a,b) left( f {xy}(a,b) ight)^2 or… …
2Bell's theorem — is a theorem that shows that the predictions of quantum mechanics (QM) are not intuitive, and touches upon fundamental philosophical issues that relate to modern physics. It is the most famous legacy of the late physicist John S. Bell. Bell s… …

9EPR paradox — In quantum mechanics, the EPR paradox is a thought experiment which challenged long held ideas about the relation between the observed values of physical quantities and the values that can be accounted for by a physical theory. EPR stands for… …
10Covariance — This article is about the measure of linear relation between random variables. For other uses, see Covariance (disambiguation). In probability theory and statistics, covariance is a measure of how much two variables change together. Variance is a …
