Derived equivalence and non-vanishing loci

The paper proposes and motivates a conjecture on the invariance of cohomological support loci under derived equivalence. It contains a proof in the case of surfaces, and explains further developments and consequences.Comment: 9 pages; to appear in the Clay volume in honor of Joe Harris' 60th birthda

A Granddaughter\u27s Admiration

Weighted exponential approximation and non-classical orthogonal spectral measures

A long-standing open problem in harmonic analysis is: given a non-negative measure $\mu$ on $\mathbb R$, find the infimal width of frequencies needed to approximate any function in $L^2(\mu)$. We consider this problem in the "perturbative regime", and characterize asymptotic smallness of perturbations of measures which do not change that infimal width. Then we apply this result to show that there are no local restrictions on the structure of orthogonal spectral measures of one-dimensional Schrodinger operators on a finite interval. This answers a question raised by V.A.Marchenko.Comment: footnote 4 is corrected; some changes are made in the proof of Theorem 2.1

Happy Self-Surrender and Unhappy Self-Assertion: A Comparison between Admiration and Emulative Envy

In this chapter, I argue that a certain kind of envy is not only morally permissible, but also, sometimes, more fitting and productive than admiration. Envy and admiration are part of our emotional palette, our toolbox of evolutionary adaptations, and they play complementary roles. I start by introducing my original taxonomy of envy, which allows me to present emulative envy, a species of envy sometimes confused with admiration. After reviewing how the two emotions differ from a psychological perspective, I focus in particular on the distinct and complementary roles they play in the ethical and political domains

Gendered identification: between idealization and admiration

While much of the literature on gender focuses on role models, this paper extends the understanding of gendered professional identification processes by exploring these processes through the lenses of idealization and admiration. Using the method of discourse analysis to analyse MBA students' accounts of people with whom they identify, this paper explores discourses of idealization, defined as aggrandizing a person, and of admiration, which means discussing positive as well as negative and neutral characteristics of a person. It is shown, first, that most male and female MBA students idealized the self-made ‘authentic’ CEO or founder of an organization and, second, that women mainly admired other women through naming their positive, neutral and negative attributes. The paper thereby adds to understanding of how gendered identification processes are structured by idealization and admiration.The authors would like to thank Rachel Dunkley Jones for helping to collect the material.

Mutual admiration clubs

This article proposes a theory of group formation based on the motive to seek informed opinion. Because an individual evaluates whether others are informed or not using his own priors, he identifies people with similar beliefs to be more informed than those with different beliefs. The result is an equilibrium in which like-minded individuals self-select into distinct groups, with members of each group believing that their own group is superior.© 2009 Western Economic Association International.postprin

Admiration regulates social hierarchy:Antecedents, dispositions, and effects on intergroup behavior

In four studies, we report evidence that admiration affects intergroup behaviors that regulate social hierarchy. We demonstrate that manipulating the legitimacy of status relations affects admiration for the dominant and that this emotion negatively predicts political action tendencies aimed at social change. In addition, we show that greater warmth and competence lead to greater admiration for an outgroup, which in turn positively predicts deferential behavior and intergroup learning. We also demonstrate that, for those with a disposition to feel admiration, increasing admiration for an outgroup decreases willingness to take political action against that outgroup. Finally, we show that when the object of admiration is a subversive “martyr,” admiration positively predicts political action tendencies and behavior aimed at challenging the status quo. These findings provide the first evidence for the important role of admiration in regulating social hierarchy
