新博物馆紧邻1967年竣工的大学艺术博物馆,是其有益扩充,并界定出新的雕塑公园和广场。新馆功能包括门厅和公共空间,永久收藏品展厅和临时藏品展厅,行政办公以及艺术维护和档案用房。新博物馆像一个紧密包裹的体块,结构形式与老建筑的相呼应,以便在全新的场地中获得清晰的组织架构。盘旋于参观者进入博物馆时头上的玻璃立面,将现有的优美的海斯小镇建筑物和雕塑公园周围的橡树反射出来。随着位置和一天中时间的不同,玻璃面在全反射和透明之间变幻。夜晚,玻璃立面被穿孔金属天花板上的筒灯染成光亮的深蓝色,使新博物馆与其老邻居形成鲜明对比。

The Catalan numbers 1, 1, 2, 5, 14, 42, 132, 429, 1430, 4862,... are given by C（n）=■for n ≥ 0. They are named for Eugene Catalan who studied them as early as *** were also found by Leonhard Euler（1758）, Nicholas von Fuss（1795）, and Andreas von Segner（1758）. The Catalan numbers have the binomial generating function ■It is known that powers of the generating function C（z） are given by ■The above formula is not as widely known as it should be. We observe that it is an immediate, simple consequence of expansions first studied by J. L. Lagrange. Such series were used later by Heinrich August Rothe in 1793 to find remarkable generalizations of the Vandermonde convolution. For the equation x-3x + 1 = 0, the numbers ■analogous to Catalan numbers occur of course. Here we discuss the history of these expansions. and formulas due to L. C. Hsu and the author.

Let {An}∞n=0 be an arbitary sequence of natural numbers. We say A（n,k;A） are the Convolution Annihilation Coefficients for {An}n∞=0 if and only if n∑κ=0A（n,k;A）（x-Aκ）n-k=xn. （0.1） Similary, we define B（n,k;A） to be the Dot Product Annihilation Coefficients for {An}n∞=0 if and only if n∑κ=0A（n,k;A）（x-Aκ）n-k=xn. （0.2） The main result of this paper is an explicit formula for B（n,k;A）, which depends on both k and {An}∞n=0. This paper also discusses binomial and q-analogs of Equations （0.1） and （0.2）.
