In this paper, topological properties of Wijsman hyperspaces are investigated. We study the existence of isolated points in Wijsman hyperspaces. We show that every Tychonoff space can be embedded as a closed subspace in the Wijsman hyperspace of a complete metric space which is locally R.

We report 60 and 90 m observations of seven millisecond pulsars with the Infrared Space Observatory. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that represent planets that failed to form or their residue. We do not detect any infrared emission from the seven pulsars in our sample, and typical upper limits are 100 mJy. Using a ...

In this paper, we show that for an almost locally separable metrizable space X, if its Wijsman hyperspace induced by one compatible metric is Baire, then X itself must be Baire. We also provide an example to demonstrate the necessity of separability.

'Space and place are central to the strategies and meaning of protest’ (p. xi) reads the opening sentence of Katrina Navickas's latest study, Protest and the Politics of Space and Place 1789–1848. Written, in part, as a response to the 'spatial turn' in History, Navickas makes a cogent and persuasive argument for attending to the importance of the particularities of 'place' rather than the abst...

In 2002 Coecke and Martin created a Bayesian order for the finite dimensional spaces of classical states in physics and used this to define a similar order, the spectral order on the finite dimensional quantum states. These orders gave the spaces a structure similar to that of a domain. This allows for measuring information content of states and for determining which partial states are approxim...

There are approximately one million kleingartens (small gardens) in Germany which provide public green spaces in urban areas. Most of the land is owned by local governments, who rent plots for approximately ¥20,000 per year to people without gardens. In Japan, on the other hand, most agricultural land in urban areas is privately owned, and unless preservation and utilization efforts are quickly...

The departure ‘space’ for this art/architecture project is the space of memories. Memories exist eternally but only in response to the lost temporal spaces they represent. Herein lies the paradox that makes any remembered space formally elusive. Thus, our first problem was determining a language/form with which to capture our own ‘remembered spaces’. We began by drawing simple floor plans of al...
