Equivariant Cohomology in Algebraic Geometry Lecture Two: Definitions and Basic Properties William Fulton Notes by Dave Anderson
For a Lie group G, we are looking for a right principal G-bundle EG → BG, with EG contractible. Such a bundle is universal in the topological setting: if E → B is any principal G-bundle, then there is a map B → BG, unique up to homotopy, such that E is isomorphic to the pullback of EG. See [Hus75] for the existence of these universal principal bundles; we will not need the general story here. W...

A new paradigm for ocean carbon observations is emerging with the rapid advances in autonomous measurements of carbon systems with the success of robotic ocean profiling Carbon Explorers, autonomous sensors for particulate organic and inorganic carbon (POC and PIC), and new instruments which will measure year-long high frequency records of POC and PIC sedimentation in the very observation-poor ...

From the start of their studies students in condensed matter physics are exposed to ordered systems. These systems can be very simple and give insight into the physics of many materials. However it seems that much of what is learned in ordered systems cannot be brought to disordered systems. Instead new conceptual understandings much be reached will very different consquences. One of these is t...

agreed-upon moral precepts, such as telling the truth and not harming others, are rules for living together that any intelligent gregarious beings would put into their social contracts, needing no divine sanction. In contrast, little good can come from parochial doctrines that cannot be justifi ed by universal standards of reason. Coyne doesn’t dwell on obvious historical disasters, such as rel...

This paper seeks to explain the shift that took place in the mid-nineteenth century elaboration of a polygenist idea of race. Supplementing existing claims that increasing evidence about the diversity of humankind provided a context for this shift, the focus here is upon British colonial encounters in Australia. It is against the background of what was considered to be a distinctly human separa...
