Let M be a symplectic manifold equipped with a Hamiltonian action of a torus T . Let F denote the fixed point set of the T -action and let i : F →֒ M denote the inclusion. By a theorem of F. Kirwan [K] the induced map i∗ : H∗ T (M) −→ H∗ T (F ) in equivariant cohomology is an injection. We give a simple proof of a formula of Goresky-Kottwitz-MacPherson [GKM] for the image of the map i∗.
This study assessed the diversity and distribution of endophytic fungal communities associated with the leaves and stems of four vascular plant species in the High Arctic using 454 pyrosequencing with fungal-specific primers targeting the ITS region. Endophytic fungal communities showed high diversity. The 76,691 sequences obtained belonged to 250 operational taxonomic units (OTUs). Of these OT...
Four new isobenzofuranones, leptosphaerins J-M (1-4), including an unusual naturally-occurring centrosymmetric dimer skeleton (1), and two new isochromenones, clearanols I-J (9-10), were obtained from a culture of a deep-sea sediment-derived fungus Leptosphaeria sp. SCSIO 41005, together with four known isobenzofuranones (5-8) and six known isochromenones (11-16). These structures were elucidat...
