Relative asymptotics and Fourier series of orthogonal polynomials with a discrete Sobolev inner product

21 pages, no figures.-- MSC2000 codes: 42C05, 33C47.MR#: MR1971776 (2004a:42035)Zbl#: Zbl 1014.42019^aLet μ be a finite positive Borel measure supported in [−1,1] and introduce the discrete Sobolev-type inner product $$\langle f,g\rangle = \int^1_{-1} f(x)g(x)d\mu(x)+\sum^K_{k=1} \sum^{N_k}_{i=0} M_{k,i} f^{(i)}(a_k)g^{(i)}(a_k),$$ where the mass points $a_k$ belong to [−1,1], $M_{k,i}\geq 0$, $i = 0,\dots,N_k-1$, and $M_{k,N_k} >0$. In this paper, we study the asymptotics of the Sobolev orthogonal polynomials by comparison with the orthogonal polynomials with respect to the measure μ and we prove that they have the same asymptotic behaviour. We also study the pointwise convergence of the Fourier series associated to this inner product provided that μ is the Jacobi measure. We generalize the work done by F. Marcellán and W. Van Assche where they studied the asymptotics for only one mass point in [−1,1]. The same problem with a finite number of mass points off [−1,1] was solved by G. López, F. Marcellán and W. Van Assche in a more general setting: they consider the constants Mk,i to be complex numbers. As regards the Fourier series, we continue the results achieved by F. Marcellán, B. Osilenker and I.A. Rocha for the Jacobi measure and mass points in R\[-1,1].The work of F. Marcellán was supported by a grant of Dirección General de Investigación (Ministerio de Ciencia y Tecnología) of Spain BFM-2000-0206-C04-01 and INTAS Project, INTAS 00-272.Publicad

Tropem magii słowa w literaturze chorwackiej i serbskiej XX wieku

The  essay  titled  „Pursuing  the  Magic  of  Words  in  the  Twentieth-Century’s  Croatian  and Serbian Literature” discusses transformations of the awareness of the avant-garde and postmodernism  from  the  perspective  of  its  relation  to  magic  thinking.  The  essay  advances a vision of poetic language and the main figures of the avant-garde’s imagination, especially the aesthetic  conceptualizations  of  the  messianic  archetype.  The  avant-garde  thinking about  the world  of  unity  (of  the  world-man-language)  is  utopian  and  not  infrequently magic-esoteric. Postmodernism deconstructs symbolic language; it does not share the avant-garde’s belief in the existential and creative power of imagination and the word. The virtual culture of postmodernism reduces the value of the language sign and the referential function of language; it disenchants the conceits of the magic word. The  essay  titled  „Pursuing  the  Magic  of  Words  in  the  Twentieth-Century’s  Croatian  and Serbian Literature” discusses transformations of the awareness of the avant-garde and postmodernism  from  the  perspective  of  its  relation  to  magic  thinking.  The  essay  advances a vision of poetic language and the main figures of the avant-garde’s imagination, especially the aesthetic  conceptualizations  of  the  messianic  archetype.  The  avant-garde  thinking about  the world  of  unity  (of  the  world-man-language)  is  utopian  and  not  infrequently magic-esoteric.

Red List and checklist of the caddisflies

Aus Berlin sind bis heute 108 Köcherfliegenarten bekannt. Davon wurden 44 Arten (41 %) in die Rote Liste aufgenommen. Die jetzige Neufassung der Roten Liste weist einige wesentliche Veränderungen gegenüber den Vorgängerlisten auf: In den früheren Versionen waren auch Arten enthalten, die nicht in Berlin, sondern im Umland der Stadt nachgewiesen wurden. Diese Arten wurden aus der Liste gestrichen. Aufgrund der schlechten Datenlage wurde in den Vorgängerlisten die Häufigkeit einiger Fließgewässerarten von Brandenburg auf Berlin übertragen. Durch das Wasserrahmenrichtlinien-Monitoring existiert heute eine deutlich bessere Datenbasis für die Fließgewässer Berlins. Dadurch kommt es zu einer abweichenden Einstufung bei einigen Arten, die nicht auf Bestandsentwicklungen beruht. Aufgrund aktueller Untersuchungen seit 2004 sind sechs Neuzugänge zu verzeichnen. Da der Altdatenbestand nicht für eine belastbare Abschätzung von Bestandstrends ausreicht, wird in der Liste auf deren Angabe grundsätzlich verzichtet.Up to now, 108 caddisfly species are known from the territory of Berlin. Of these, 44 species (41 %) are included in the Red List. The actual version of the Red List contains some significant changes compared to previous lists. Earlier lists included some species recorded not in Berlin but in the surroundings of the city. These species were removed from the present list. Due to the lack of sufficient data, the abundance of some species with larvae in flowing water in Berlin was inferred from the abundance in Brandenburg. Investigations in the framework of the federal water guideline have led to a clear improvement of data. This resulted in a different classification of some species that is not related to changes in the abundance. Since 2004, six species were recorded for the first time in Berlin. No trends are presented in the current Red List because the dataset of older records is insufficient for assessing trends in abundance

Pythagoras and the (Were)Wolf

This article examines some complex connections between Pythagorean symbolism and related aspects of ancient Greek mythology concerning wolves, lycanthropy, the colour white, music, Mt. Lykaion in Arcadia, the gods Zeus, Apollo, Artemis and Pan as well as ancient mystical rites of initiation and the philosopher Plato. These connections are at times obscure but well attested in the sources. The article goes through each of them in turn and demonstrates their connectivity, along with broader implications in the mythology of the Near East

Survey and Geoarcheological assessment of a Megafauna Locality along the Loop 88 Project, Lubbock County, Texas

The Texas Department of Transportation (TxDOT) proposes to construct a new loop along a portion of the existing Farm-to-Market Road (FM) 1585 from 0.5 miles northwest of US 62/82 to 0.5 miles east of US 67 in Lubbock, Texas. The overall Loop 88 Project has a length of approximately 12.38 miles with a width that varies from approximately 150 feet to 300 feet and an area of potential effects (APE) consisting of 736.6 acres. Based on the recommendations of a prior survey conducted under Texas Antiquities Permit 8023, the current investigation examined a 0.2 acre portion of the overall 736.6 acre APE. The survey area is approximately 0.23 miles east of the intersection of FM 1585 and FM 179 immediately north of the FM 1584 roadway. TxDOT conducted the Intensive Archeological Survey and Georcheological Assessment of the 0.2 acre area within existing and proposed new ROW of the Loop 88 Project in Lubbock County, Texas. No previously recorded archeological sites are recorded within the project area although the discovery of fossil mammal remains near a playa 0.23 miles east of the intersection of FM 1585 and FM 179 (under Permit 8023) necessitated the current survey and geoarcheological evaluation. Gradall scraping was proposed to relocate the prior trenches, reach the depth of the purported finds, and carefully scrape to assess presence or absence of additional elements. During the archeological survey and georcheological assessment of the location presently identified as the Megafauna Locality, the investigations yielded additional disarticulated megafauna remains thought to be mammoth and possibly bison. Pleistocene megafauna remains have been found in archeological sites in the region such as Lubbock Lake, Plainview, and Miami Texas. As such, TxDOT is proceeding cautiously given the potential for a site of considerable antiquity. Given the unusual nature of the find, TxDOT is recommending the Megafauna Locality be treated as eligible for listing to the National Register of Historic Places (36 CFR 800.16(l)) and designation as a State Antiquities Landmark (13 TAC 26.12)
