The gauge action, DG Lie algebra and identities for Bernoulli numbers

In this paper we prove a family of identities for Bernoulli numbers parameterized by triples of integers $(a,b,c)$ with $a+b+c=n-1$, $n\ge 4$. These identities are deduced while translating into homotopical terms the gauge action on the Maurer Cartan Set which can be seen an abstraction of the behaviour of gauge infinitesimal transformations in classical gauge theory. We show that Euler and Miki's identities, well known and apparently non related formulas, are linear combinations of our family and they satisfy a particular symmetry relation.Comment: Small modifications.

Immigration at the extremes of the skill distribution

According to economists, in the 1980s and 1990s, immigration of low-skilled workers may have increased the labor supply of highly skilled women, and immigration of highly skilled workers may have increased the rate of innovation in the United States.Immigrants ; Labor supply - United States

Which came first—better education or better health?
