The large diversity of floral displays in angiosperms has been attributed largely to natural selection exerted by animal pollinators (Darwin, 1859; Grant and Grant, 1965; Waser, 1983). Quantitative measurements of selection on floral traits have only been made recently, however, and only on a handful of plant species (Campbell, 1989; Galen, 1989; Schemske and Horvitz, 1989; Campbell et al., 199...

Boardman’s work [3,4] on Conner and Floyd’s five-halves conjecture looks remarkably contemporary in retrospect. This note reexamines some of that work from a perspective proposed recently by Greenlees and Kriz. 1. Unoriented involutions A large part of Boardman’s argument can be summarized as a commutative diagram 0 // N geo Z/2Z∗ // ⊕i≥0Ni(BO∗−i) ∂ //

It has been known for many years that disease of the superior mesenteric artery can produce abdominal pain and other chronic symptoms in the absence of gangrene of the bowel or peritonitis (Klein, I921; Conner, 1933; Hertzler, 1935; Seymour and Liebow, I937), and that inevitably these symptoms terminate in acute bowel infarction. However, it is only recently, as the feasibility of direct arteri...

This paper summarizes and comments on Conner (1991) that contributes to the strategic management area by providing an historical comparison of resource-based theory and five schools of thought within industrial organization economics. Conner (1991) argues that the fundamental distinction between resource-based theory and transaction costs theory is that resource-based theory focuses on the depl...

For quadratic fields whose discriminant has few prime divisors, there are explicit formulas for the 4-rank of K2OE . For quadratic fields whose discriminant has arbitarily many prime divisors, the formulas are less explicit. In this paper we will study fields of the form Q[ √ p1 · · · pk], where the primes pi are all congruent to 1 mod 8. We will prove a theorem conjectured by Conner and Hurrel...

We present geometric constructions which realize the local cohomology filtration in the setting of equivariant bordism, with the aim of understanding free G actions on manifolds. We begin by reviewing the basic construction of the local cohomology filtration, starting with the Conner-Floyd tom Dieck exact sequence. We define this filtration geometrically using the language of families of subgro...
