Organismal Differentials and Organ Differentials.

On Method of Statistical Differentials

The method of statistical differentials, which approximates the mean value and variance of transformations of random variables is used in many areas of mathematics. This paper will discuss the conditions under which such an approximation will be exact, and also explore their accuracy in terms of error bounds under certain moment conditions.

On Evgrafov-fedoryuk’s Theory and Quadratic Differentials

The purpose of this note is to recall the theory of the (homogenized) spectral problem for Schrödinger equation with a polynomial potential and its relation with quadratic differentials. We derive from results of this theory that the accumulation rays of the eigenvalues of the latter problem are in 1 − 1-correspondence with the short geodesics of the singular planar metrics induced by the corre...

On class differentials in educational attainment.

Social class differentials in educational attainment have been extensively studied in numerous countries. In this paper, we begin by examining class differentials in the progression to higher secondary education among 16-year-old children in England and Wales. As has been shown for other countries, the differentials result both from the primary effects of differing levels of academic performanc...
