It is traditionally constructed by laying bricks lengthwise over a wood form or centering , making it a much gentler curve than has generally been produced by other methods of construction. It is a traditional form in Catalonia where it is widely used , and has spread around the world through the work of Catalan people Catalan architect s such as Gaud Antoni Gaud and Josep Puig i Cadafalch . A study on the stability of the Catalan vault is kept at the archive of the Institut d Estudis Catalans Institute of Catalan Studies , where it is said to have been entrusted by Josep Puig i Cadafalch. Though it is popularly called the Catalan vault, this construction method is found throughout the Mediterranean and the invention of the term Catalan vault occurred in 1904 at an architectural congress in Madrid.

Catalan s conjecture or Mih ilescu s theorem is a theorem in number theory that was conjectured by the mathematician Eug ne Charles Catalan in 1844 and proven in 2002 by Preda Mih ilescu . 2 sup 3 sup and 3 sup 2 sup are two perfect power power s of natural number s, whose values 8 and 9 respectively are consecutive. The conjecture states that this is the only case of two consecutive powers. That is to say, that the only Diophantine equation solution in the natural numbers of x sup a sup y sup b sup 1 for x , a , y , b > 1 is x 3, a 2, y 2, b 3. History The history of the problem dates back at least to Gersonides , who proved a special case of the conjecture in 1343 where x and y were restricted to be 2 or 3. In 1976, Robert Tijdeman applied methods from the theory of transcendental number ... had established a bound for the base dependent only on the exponents, this resolved Catalan s conjecture ... the proof of the theorem was nonetheless too time consuming to perform.

Arnaut Catalan floruit fl. 1219&ndash 1253 was a troubadour active in the Languedoc , Catalonia , and Castile historical region Castile . He left behind five Canso song cansos , three tenso s , and one religious song. Arnaut s origins are disputed. Most Catalan people Catalan scholars, such as Mil and Fontanals, believe him to be a Catalan, hence his nickname. Others, such as Chabaneau, assign him to a prominent family from Toulouse named Catalan . If the latter is correct he is probably the same as the Dominican Order Dominican Inquisitor who persecuted Cathars with such force that he was almost killed by a mob in Albi in 1234.

Image Llu s Pujals Tible.jpg 300px right In music, a Catalan shawm is one of two varieties of shawm an oboe like woodwind instrument played in Catalonia in northeastern Spain. Region, types, and uses The types of shawm commonly used in Catalonia are the tible IPA ca tib pron , Catalan language Catalan for treble and the tenora IPA ca t no pron , Catalan for tenor . The tenora is pitched about a fifth lower than the tible. These shawms are usually used with other instruments to accompany the traditional Catalan circle dance, the Sardana . Other Catalan folk shawms are the tarota IPA ca t t pron the original keyless version of the tible , and the gralla IPA ca a pron , a short, strident instrument with a steep conical bore. Both of these resemble shawms from other parts of Spain, such as the dulzaina dol aina of Aragon and Valencia, and both employ open fingering. Difference between shawms and oboes There are several distinct differences between shawms and oboe s. Shawms normally have a larger bore, which makes them louder and more suitable than the oboe for outdoor playing. In addition, the bore is more sword shaped than that of the oboe it is more like a narrow parabola than a perfect cone . This gives the shawm a stronger, earthier, more fiery tone. Though favored in ancient times, some today find the sound harsh and irritating. The difference in bore shape also gives shawms additional problems with Intonation music intonation . It was the goals of easier fingering, better intonation, and a sound and volume level more suitable for indoor use that prompted the innovations that turned the shawm into the oboe. The tible and tenora, however, were modernized without ... the shawms very durable.

Image Rhombic dodecahedron.jpg thumb A rhombic dodecahedron In mathematics , a Catalan solid , or Archimedean dual , is a dual polyhedron to an Archimedean solid . The Catalan solids are named for the Belgium Belgian mathematician, Eug ne Catalan , who first described them in 1865. The Catalan solids are all convex. They are face transitive but not vertex transitive . This is because the dual Archimedean solids are vertex transitive and not face transitive . Note that unlike Platonic solid s and Archimedean solid s, the faces of Catalan solids are not regular polygon s. However, the vertex figure s of Catalan solids are regular, and they have constant dihedral angle s. Additionally, two of the Catalan solids are edge transitive the rhombic dodecahedron and the rhombic triacontahedron . These are the Quasiregular polyhedron Quasiregular duals duals of the two Quasiregular polyhedron quasi regular Archimedean solids. Two of the Catalan solids are chirality mathematics chiral the pentagonal icositetrahedron and the pentagonal hexecontahedron , dual to the chiral snub cube and snub dodecahedron ... there are a total of 13 Catalan solids. class wikitable sortable Name s Picture BR Solid Picture BR ... dual uniform polygonal tilings similar to the Catalan solids Conway polyhedron notation A notational construction process Archimedean solid Johnson solid References Eug ne Catalan M moire sur la Th orie ... book Section 3 9 External links commons category Catalan solids MathWorld urlname CatalanSolid title Catalan Solids GlossaryForHyperspace anchor Catalan title Catalan http www.georgehart.com virtual ... ibiblio.org e notes 3Dapp Catalan.htm Interactive Catalan Solid in Java DEFAULTSORT Catalan Solid Category Catalan solids bar Catalanischa Keapa ca Pol edre de Catalan de Catalanischer K rper es S lidos de Catalan eo Kataluna solido fr Solide de Catalan it Solido di Catalan nl Catalan lichaam ja no Katalansk legeme nn Katalansk lekam pl Wielo ciany Catalana pt S lidos de Catalan zh ... more details
In combinatorics combinatorial mathematics , Catalan s triangle is a number triangle , where entry C sub n,k sub denotes the number of strings consisting of n X s and k Y s such that no initial segment of the string has more Y s than X s.

The Catalan counties lang ca Comtats catalans , IPA ca kum tats k t ans IPA were the administrative divisions of the eastern Carolingian Marca Hispanica created after its Franks Frankish conquest. The various counties roughly defined what came to be known as the Principality of Catalonia . In 778, Charlemagne led his first expedition into Hispania . The territory that he subjugated to his rule was the kernel of Catalonia. In 781, he created his son Louis the Pious King of Aquitaine with the mandate to defend and extend the southern border against the Moors . In 785, Rostaing was made Count of Girona , the first of the established Catalan counties. In 797, in the greatest military triumph of his long career, the young Louis took Barcelona , the greatest city of the Catalan littoral. In 798, county of Urgell Urgell , county of Osona Osona , and county of Cerdanya Cerdanya were established under Borrell of Ausona Borrell . In 801, the greatest of the counties, Barcelona, was established under Bera, Count of Barcelona Bera . Barcelona soon overshadowed the other counties in importance, especially through the reign of Wilfred the Hairy in the late ninth century. At that time, the power of the Carolingians was waning and the neglected Hispanic march was practically independent of royal authority. In the early eleventh century, Berenguer Ramon I, Count of Barcelona , was able to submit to Sancho III of Navarre as his suzerain, even though he was still legally a vassal of Robert II ..., most of the Catalan counts had refused to do homage to the new dynasty.
