We show that the intrinsic Baire classes of X can be identified with the spaces of odd Baire functions on the set ext BX∗ of the extreme points of the dual unit ball BX∗ in the case when ext BX∗ satisfies some topological assumptions. This generalizes results of Lindenstrauss andWulbert from [On the classification of the Banach…
Let G be a finite primitive permutation group and let κ(G) be the number of conjugacy classes of derangements in G. By a classical theorem of Jordan, κ(G) 1. In this paper, we classify the groups G with κ(G) = 1, and we use this to obtain new results on the structure of finite groups with an irreducible complex character that vanishes on a unique conjugacy class. We also obtain…
Deformation experiments on partially molten rocks in simple shear form melt bands at 20◦ to the shear plane instead of at the expected 45◦ principal compressive stress direction. These melt bands may play an important role in melt focusing in mid-ocean ridges. Such shallow bands are known to form for two-phase media under shear if strongly non-Newtonian power-law creep is employed …
American medievalist buildings of the Gilded Age often reinterpreted historical forms in new idioms inflected by modern architectural developments. Nevertheless, some of their makers remained keenly aware of issues of authenticity and struggled to create truly medieval experiences for their American audiences. This essay explores the discourse of authenticity as it influenced the architectural …
The arrival of Georg Swarzenski at the Museum of Fine Arts in Boston opened a formative chapter for one of the most significant medieval collections on American soil. In a tremendously ambitious enterprise, which would be continued by his son Hanns after his retirement, Georg Swarzenski amassed a collection of significant quantity and outstanding quality in a surprisingly brief span of time. W…
Media mogul and art collector William Randolph Hearst was once described by Joseph Duveen as ‘the great accumulator’. Hearst’s holdings were indeed vast, catholic, and surprisingly personal, but it would be incorrect to assume they were largely inferior in quality (an impression encouraged by Orson Welles’s thinly veiled portrait of Hearst in Citizen Kane): he bought art nearly all his …
A general method of solution for the runup evolution and some analytical results concerning a more general bathymetry than a canonical sloping beach model are presented. We studied theoretically the water wave elevation and runup generated on a continuous piecewise linear bathymetry, by solving analytically the linear shallow water wave equations in the 1+1 dimensional case. Non-horizontal line…
As the first large subduction thrust earthquake off the coast of western Guatemala in the past several decades, the 2012 November 7 Mw = 7.4 earthquake offers the first opportunity to study coseismic and postseismic behaviour along a segment of the Middle America trench where frictional coupling makes a transition from weak coupling off the coast of El Salvador to strong coupling in southern Me…
From the fourteenth century until the end of the eighteenth century, almost every town of the Kingdom of Naples had one or more Seggi where the main families used to meet in order to take decisions about the city governement. The Seggi were also the preferred places for locating antiquities and ancient inscriptions of the towns. This paper analyzes the character of such collections, focusing on…
