Affine Pieri rule for periodic Macdonald spherical functions and fusion rings
No full textLet gˆ be an untwisted affine Lie algebra or the twisted counterpart thereof (which excludes the affine Lie algebras of type BCˆn=A2n(2)). We present an affine Pieri rule for a basis of periodic Macdonald spherical functions associated with gˆ. In type Aˆn−1=An−1(1) the formula in question reproduces an affine Pieri rule for cylindric Hall-Littlewood polynomials due to Korff, which at t=0 specializes in turn to a well-known Pieri formula in the fusion ring of genus zero slˆ(n)c-Wess-Zumino-Witten conformal field theories.Applied Probabilit
Kraśkiewicz-Pragacz Modules and Pieri and Dual Pieri Rules for Schubert Polynomials
No full textIn their 1987 paper Kra\\u27skiewicz and Pragacz defined certain modules \smod_w (), which we call KP modules, over the upper triangular Lie algebra whose characters are Schubert polynomials. In a previous work the author showed that the tensor product of KP modules always has a KP filtration, i.e. a filtration whose each successive quotients are isomorphic to KP modules. In this paper we explicitly construct such filtrations for certain special cases of these tensor product modules, namely \smod_w \otimes S^d(K^i) and \smod_w \otimes \bigwedge^d(K^i), corresponding to Pieri and dual Pieri rules for Schubert polynomials

Skew Pieri Rules for Hall-Littlewood Functions
No full textInternational audienceWe produce skew Pieri Rules for Hall–Littlewood functions in the spirit of Assaf and McNamara (FPSAC, 2010). The first two were conjectured by the first author (FPSAC, 2011). The key ingredients in the proofs are a q-binomial identity for skew partitions that are horizontal strips and a Hopf algebraic identity that expands products of skew elements in terms of the coproduct and antipode.Nous produisons quelques règles dissymètrique de Pieri pour les fonctions Hall–Littlewood au sens de Assaf et McNamara (FPSAC, 2010). Les premières deux règles ont ètè conjecturèe par le premier auteur (FPSAC, 2011). Les principaux ingrèdients dans les preuves sont une identitè q-binomiale pour les partitions dissymètrique qui sont bandes horizontales et une identitè de Hopf qui exprime les produits d'èlèments dissymètrique en termes du coproduit et de l'antipode

Dystopia as a narrative keyword: Tawada Yōko’s responses to Japanese 3/11
No full textOn 11th March 2011 at 2:46 PM the Japanese writer Tawada Yōko was in Berlin, miles away from her Japanese homeland. Still, the author got affected by the 9 magnitude earthquake that stroke Tōhoku coast at that time. As the tsunami came to shore wiping out everything that was spared by the quake, the aftershocks reached Tawada and now reverberates in some of her last new literary works. First, Fushi no Shima (“The Island of the Eternal Life”) published in the collection Sore demo sangatsu wa, mata : a ten-page story about a no more lively island, namely, Japan. Then, after years of muteness regarding the Daishinsai topic, the 2014 collection of novels published under the evocative title Kentōshi (“The messenger of the votive lantern”) resonates the echo of that aftermath again : Tawada imagines a forthcoming catastrophic scenario clearly influenced by 2011 disaster. The dystopian keyword adopted by the author for these post-Fukushima narratives represents a camera lens through which the writer observes Japanese 11th March. This brief article aims to investigate these two Tawada Yōko’s responses to Japanese 3/11 with the aid of the journal the author wrote during those days and published under the French title Journal des jours tremblants : Après Fukushima
Wird irgendetwas mit mir geschehen? Psycho(patho)logical perspectives on Hannah Arendt’s The Banality of Evil
No full textIn 1961, the Eichmann trial opened in Jerusalem, and its worldwide resonance through media coverage questioned the collective conscience about responsibility for Nazi crimes. German philosopher Hannah Arendt attended the process as a special correspondent for the U.S. magazine The New Yorker. Her Eichmann in Jerusalem: A Report on the Banality of Evil (1963) caused a great scandal: the author advanced the brazen idea of collective co-responsibility for Nazi crimes, reporting the identikit of a standard bureaucrat, a seemingly ordinary man, just like any one of us. Almost sixty years after its publication, this study adopts a primarily psycho(patho)logical perspective to reflect once again on the considerations Arendt shared in the Banality of Evil. In showing the multiple facets of banality, the research investigates recent results in the analysis of the criminal mind in order to shed light on the etiology of evil
Remarks on the paper "Skew Pieri rules for Hall-Littlewood functions" by Konvalinka and Lauve
No full textIn a recent paper Konvalinka and Lauve proved several skew Pieri rules for Hall-Littlewood polynomials. In this note we show that q-analogues of these rules are encoded in a q-binomial theorem for Macdonald polynomials due to Lascoux and the author
Anzen ka, kiken ka: radiation anxiety in the multilingual Hamlet No See by Tawada Yōko
No full textTawada Yōko has enjoyed international acclaim in recent years for her eclectic production that overcomes ethnic and linguistic barriers to constitute a universal language that is the literary one. This contribution analyzes the poem Hamlet No See (2011?), written in Japanese/English and translated into German by the author, which constitutes a ground for intertextual experimentation through the revival of cross-cultural elements such as Shakespeare's Hamlet.
After a brief introduction related to the role of multilingualism in the expression of psychological trauma, the study aims to investigate how the multilingualism performed by Tawada in her poem can assist in verbalizing the post-Fukushima radiation anxiety in the attempt to overcome the inexplicable
