Parity current and parity representation
Il Nuovo Cimento A, 1976We introduce the concept of parity current and relate its derived « charge » to an explicit representation of the parity transformation (in terms of field variables) in an analogous way that the « charge » of a current arising from a continuous transformation of the fields is related to an explicit representation of a continuous transformation.

The concept of parity conservation is the quantum mechanical expression of the intuitively reasonable hypothesis that the laws of physics do not distinguish between a system and its mirror image. This article attempts to provide a nonmathematical account of the importance of conservation laws in elementary-particle physics and the way in which this ...

Striving for maximum diversification we follow the 2009 work of Meucci in measuring and managing a multi-asset class portfolio. Under this paradigm the maximum diversification portfolio is equivalent to a risk parity strategy with respect to the uncorrelated risk sources embedded in the underlying portfolio assets.

Risk parity is portfolio construction technique that, using risk alone, scales each part of a portfolio — e.g., stocks, bonds, currencies, commodities — so that its contribution to net portfolio risk matches its budgeted risk. Because risks are measured using a point-estimate of covariance, the method is subject to problems of estimation error.
