We report Australia Telescope Compact Array (ATCA) radio-continuum and ROSAT PSPC X-ray observations of the region surrounding the peculiar galaxy pair ESO 295-IG022, lying at the centre of the poor cluster Abell S0102. We identify a radio galaxy coincident with the galaxy pair, with bipolar, bent radio jets appearing centred on the southern galaxy, and extending both to the south, for about 95...

Abstract The peakons and mulit-peakons for a generalized cubic–quintic Camassa–Holm type equation have been obtained by Weng et al. (Monatsh Math, 2022. https://doi.org/10.1007/s00605-022-01699-w ). In this paper, constructing certain Lyapunov functionals, we prove that the were orbitally stable in energy space. Furthermore, using argument combining method of orbital stability with monotonicity...

A pure exchange economy generates a “market game” in which the allocations achievable by any coalition are determined by the initial endowments of its members. Subject to certain regularity conditions, it is shown that for a market game it is possible to find utility representations for each consumer so that the game can be treated as a game with transferable utility if and only if indirect uti...

This paper examines existence, continuity and characterization of optimal paths under “recursive” preferences. Current utility is a fixed (aggregator) function of current consumption and future utility. For suitable aggregators, a useful refinement of the Contraction Mapping Theorem generates the utility function, as in Lucas and Stokey. A broader class of aggregators is handled via a limiting ...

Subgame-perfect equilibria are characterized for a market in which the seller quotes a price each period. Assume zero costs, positive interest rate, continuum of buyers, and some technical conditions. If buyers’ valuations are positive then equilibrium is unique, buyers’ strategies are stationary, and the price sequence is determinant along the equilibrium path but possibly randomized elsewhere...
