In this note we introduce and investigate the concepts of dual entwining structures and dual entwined modules. This generalizes the concepts of dual Doi-Koppinen structures and dual Doi-Koppinen modules introduced (in the infinite case over rings) by the author is his dissertation.

We construct recently introduced palatial NC twistors by considering the pair of conjugated (Born-dual) twist-deformed D=4 quantum inhomogeneous conformal Hopf algebras U?(su(2,2)?T4) and U?¯(su(2,2)?T¯4), where T4 describes complex twistor coordinates T¯4 dual momenta. The are suitably chosen as quantum-covariant modules (NC representations) Born-dual algebras. Subsequently, we introduce defor...

In this article we show that all periods of uniformizable $t$-modules (resp. their coordinates) can be obtained via specializing a rigid analytic trivialization related dual $t$-motive at $t=\theta$. The proof is even constructive. central object in the construction subset $H$ Tate algebra points $E$ which turns out to isomorphic period lattice kind generating series one direction and residues ...

The author and Nakano recently proved that multiplicities in a Specht filtration of a symmetric group module are well-defined precisely when the characteristic is at least five. This result suggested the possibility of a symmetric group theory analogous to that of good filtrations and tilting modules for GLn(k). This paper is an initial attempt at such a theory. We obtain two sufficient conditi...

OBJECTIVE To determine the brainstem auditory evoked response (BAER) abnormalities and their reversibility in neonates with birth asphyxia. DESIGN Prospective case control study. SETTING Tertiary care teaching hospital. METHODS 30 term Neonates with 5-min Apgar < 6 and hypoxic ischemic encephalopathy (HIE) underwent BAER testing with follow up at 3 months. An equal number of normal term n...
