Dold-Thom functors are generalizations of infinite symmetric products, where integer multiplicities of points are replaced by composable elements of a partial abelian monoid. It is well-known that for any connective homology theory, the machinery of Γ-spaces produces the corresponding linear Dold-Thom functor. In this note we show how to obtain such functors directly

The increase in wage inequality in Russia during its transition process has far exceeded the increase in wage dispersion observed in other European countries undergoing transition. Russia also has an extremely large incidence of wage arrears. We analyse to what extent wage arrears affect the wage distribution and measures of wage inequality in Russia. We present counterfactual distributions, de...

We give a Pontryagin-Thom type construction for −1-codimensional fold maps. We obtain results about cobordism and bordism groups of fold maps of oriented (n+1)-dimensional manifolds into n-dimensional manifolds in an analogous way to the Pontryagin-Thom type construction for positive codimensional singular maps.

Comet C/2002 X5 (Kudo-Fujikawa) was observed near its perihelion of 0.19 astronomical unit by the Ultraviolet Coronagraph Spectrometer aboard the Solar and Heliospheric Observatory spacecraft. Images of the comet reconstructed from high-resolution spectra reveal a quasi-spherical cloud of neutral hydrogen and a variable tail of C+ and C2+ that disconnects from the comet and subsequently regener...
