Let V be a finite dimensional complex vector space. A finite subgroup G ⊂ GL(V ) is called a complex reflection group, if G can be generated by the set of pseudoreflections, i.e., transformations that fix a complex hyperplane in V pointwise. Any real reflection group becomes a complex reflection group if one extends the scalars from R to C. In particular all Coxeter groups give examples of comp...

For example among the gastropods 80% of the species found in the lake are endemic. Most diversity is displayed in the family Thiaridae. The genus Lavigeria it is the most common thiarid genus and at the same time the most diverse (Michel 1995). It has an estimated species diversity of 20 or more endemic species (Michel & Todd, in prep). The often sympatric species show many shell morphological ...

We explore whether the recent laboratory findings that suggest the origin of endowment matters in simple bargaining games are actually due to contextual shifts of relative effort and deservingness. Results support previous findings of endowment origin yielding more self-interested behavior. Todd L. Cherry & Jason F. Shogren (2008) "Self-Interest, Sympathy And The Origin Of Endowments" Economic ...

To understand the relative importance of various incentives for subprime borrowers to default on their mortgages, we build an econometric model that nests various potential drivers of borrower behavior. We allow borrowers to default on their mortgages either because doing so increases their lifetime utility or because of the borrowers’ inability to pay, treating the decision as the outcome of a...

We give some connections between various functions defined on finitely presented groups (isoperimetric, isodiametric, Todd-Coxeter radius, filling length functions, etc.), and we study the relation between those functions and the computational complexity of the word problem (deterministic time, nondeterministic time, symmetric space). We show that the isoperimetric function can always be linear...

Over the past several decades in the US, married women’s hours of market work increased significantly. I argue that changes in behavior by married women with children account for much of this change. In particular, the pattern of married women’s work hours over the life cycle has changed substantially. In the past, married women of childbearing age tended to specialize in childrearing and home ...

This paper examines career choices using a dynamic structural model that nests a job search model within a human capital model of occupational and educational choices. Wage growth occurs in the model because workers move between …rms and occupations as they search for suitable job matches and because workers endogenously accumulate …rm and occupation speci…c human capital. Simulations performed...

Here {y\ = y — [y] = the fractional part of y. The number N is an integer >1. The number x0 is a given initial value such that 0 ^ Xo < 1. The number 0 is fixed. Some early references to numerical work with sequences of the type (1) are given by 0. Taussky and J. Todd in [1]. Regarding the sequence x„ as a function of Xo, I proved in [2] that for almost all x0 the sequence x„ is equidistributed...
