Politeness and Stable Infiniteness: Stronger Together

Stronger Together : Nutrition - Disability Links and Synergies

Malnutrition and disability are both major global health problems. There are an estimated one billion people worldwide living with a disability of whom some 93 million are children aged under 14 years. Worldwide, almost one billion people are malnourished. Malnutrition remains a major cause of child mortality, with the latest estimates suggesting that undernutrition causes 3.1 million child dea...

WIMPs Are Stronger When They Stick Together

Weakly interacting massive particles (WIMPs) remain the strongest candidates for the dark matter in the Universe. If WIMPs are the dark matter, they will form galactic halos according to the hierarchical clustering observed in N-body simulations. Cold dark matter (CDM) simulations show that large dark matter structures such as galactic and cluster halos are formed by the merging of many smaller...

Homological Infiniteness of Torelli Groups

1 → I g,r → M n g,r → Sp(2g,Z) → 1. We omit the decorations n and r when they are zero. In a series of papers [7, 8, 9, 10], D. Johnson obtained several fundamental results concerning the structure of Ig and Ig,1 (see also [11, 2]). In particular, he proved that Ig and Ig,1 are finitely generated for all g ≥ 3. On the contrary, A. Miller and D. McCullough [14] showed that I2 (and hence I n 2,r ...
