The Centrosymmetric-Noncentrosymmetric Ambiguity: Some More Examples

Four more examples are provided to emphasize the extreme difficulty in deciding, by diffraction methods, whether a crystal structure is centrosymmetric or only approximately so. In these examples, earlier workers described and refined structures in noncentrosymmetric space groups; refinements in the corresponding centrosymmetric space groups, based on the original data, lead to improved results...

Some more Marx Concept examples:

Democracy: Marx’s theory of history (ex. Organization of the mode of production determines superstructure; unequal distribution of labor) explains the lack of actual democracy in capitalist societies; however, Marx’s thought concerning progression (also a theory of history) states that capitalist societies would eventually progress to a democratic state after a revolution of the proletariat. Ma...

Recursive Ambiguity and Machina's Examples

Machina (2009, 2012) lists a number of situations where standard models of ambiguity aversion are unable to capture plausible features of ambiguity attitudes. Most of these problems arise in choice over prospects involving three or more outcomes. We show that the recursive non-expected utility model of Segal (1987) is rich enough to accommodate all these situations. JEL Classification number: D81

More Examples

Some important examples and explications of Grothendieck duality which should have been included in Chapter 5 of [C1] were overlooked. Several such topics are treated here. One question which can be asked about the trace map H(X,ΩX/k) → k for a proper smooth scheme X of pure dimension n over a field k is how it relates to the trace map for a smooth divisor. Generalizing a little, one can ask wh...
