On some applications of unstable Adams operations to the topology of Kac-Moody groups

Localized at almost all primes, we describe the structure of differentials in several important spectral sequences that compute the cohomology of classifying spaces of topological Kac-Moody groups. In particular, we show that for all but a finite set of primes, these spectral sequences collapse and that there are no additive extension problems. We also describe some appealing consequences of these results. The main tool is the use of the naturality properties of unstable Adams operations on these classifying spaces.Comment: The construction of the local unstable Adams operation, needed for the proof of the main theorem, that was implicit in Section 3 has now been presented explicitly as a new sectio

Optimal financial structure, bankruptcy risk and the right to a new beginning

Starting from the need to optimize the financial structure of the enterprise, the article aims to review a few concepts related to financial structure and bankruptcy risk, the presentation of the bankruptcy risk analysis based on assets balance sheet, liquidity ratios and last, but not least, scoring method. It also presents some points of view regarding the current economic crisis and the evolution of national and international level approaches about bankruptcy and the risk of bankruptcy.financial structure, bankruptcy risk, liquidity ratios

Hungarian small and medium enterprises’ strategies and their effects on the economic performance

Abstract The impact of large company’s strategy on its performance constitutes an interesting subject for the strategic management research.  There is little attention given to the analysis of this relationship at the small and medium enterprise (SME) scale and even less studies published to examine it from a regional perspective. The aim of this study is to empirically investigate the link between strategies and performance of SME’s. Data for the research were obtained primarily from a survey of SMEs conducted in Hungary. Results indicate that the different indicators of financial performance of SMEs are having a strong link with the firm’s strategy, while the firm regional location may have a limited influence, depending on financial indicators. The findings of this study might be useful to managers of Hungarian SMEs, while contributing to the SMEs field research

On fibrations related to real spectra

We consider real spectra, collections of Z/(2)-spaces indexed over Z oplus Z alpha with compatibility conditions. We produce fibrations connecting the homotopy fixed points and the spaces in these spectra. We also evaluate the map which is the analogue of the forgetful functor from complex to reals composed with complexification. Our first fibration is used to connect the real 2^{n+2}(2^n-1)-periodic Johnson--Wilson spectrum ER(n) to the usual 2(2^n-1)-periodic Johnson--Wilson spectrum, E(n). Our main result is the fibration Sigma^{lambda(n)} ER(n) --> ER(n) --> E(n)$, where lambda(n) = 2^{2n+1}-2^{n+2}+1.Comment: This is the version published by Geometry & Topology Monographs on 27 January 200
