Hilbert Schemes of Degree Four Curves
In this paper we determine the irreducible components of the Hilbert schemes H4,g of locally Cohen-Macaulay space curves of degree four and arbitrary arithmetic genus g. We show that these Hilbert schemes are connected, in spite of having ∼ g 2 24 irreducible components. For g ≤ −3 we exhibit a component that is disjoint from the component of extremal curves and use this to give a counterexampl...
متن کاملDegree Reduction of Disk Wang-Bézier Type Generalized Ball Curves
A disk Wang-Bézier type generalized Ball curve is a Wang-Bézier type generalized Ball curve whose control points are disks in a plane. It can be viewed as a parametric curve with error tolerances. In this paper, we discuss the problem of degree reduction of disk Wang-Bézier type generalized Ball curve, that is, bounding disk Wang-Bézier type generalized Ball curves with lower degree disk Wa...

متن کاملSixty-four or four-and-sixty? The influence of language and working memory on children's number transcoding
Number transcoding (e.g., writing 64 when hearing "sixty-four") is a basic numerical skill; rather faultlessly performed in adults, but difficult for children. In the present study, children speaking Dutch (an inversed number language) and French (a non-inversed number language) wrote Arabic digits to dictation. We also tested their IQ and their phonological, visuospatial, and executive working...
متن کاملSix sixty-six and all that (or, what the hell is marketing eschatology?)
In the beginning was the word... And the word was eschatology Words, according to the late, great novelist, Evelyn Waugh, "should be an intense pleasure, just as leather should be to a shoemaker". Like the apocrj^hal author whose lifetime ambition was to write a book that ended with the word "mayonnaise", or H.L. Mencken's famous contention that the words "cellar door" comprise the most euphoni...
