Mirror Symmetry of K3 and Torus
We discuss a K3 and torus from view point of "mirror symmetry". We calculate
the periods of the K3 surface and obtain the mirror map, the two-point
correlation function, and the prepotential. Then we find there is no instanton
correction on K3 (also torus), which is expected from view point of Algebraic
geometry.Comment: 21 pages, UT-663, LaTex fil
The dynamics of wind-driven intraseasonal variability in the equatorial Indian Ocean
This commentary provides a discussion of the concept of `bounded rationality' as it applies to the theses advanced by Lopes (1991) and Evans (1991). Lopes's (1991) assessment of the irrationalist consequences of Tversky and Kahneman's (1974) work on heuristics and biases is premature because bounded rationality implies that people could not employ optimal strategies. Considerations of bounded rationality also provide additional criteria by which to judge the theories of deductive reasoning discussed by Evans (1991). Judged by this criterion, theories whose goal is to explain logically competent performance are inadequate (Oaksford & Chater, 1991). Thus Evans's assessment of the state of current theories of reasoning requires revision
