Maximal Tychonoff Spaces and Normal Isolator Covers
We introduce a new kind of cover called a normal isolator cover to characterize maximal Tychonoff spaces. Such a study is used to provide an alternative proof of an interesting result of Feng and Garcia-Ferreira in 1999 that every maximal Tychonoff space is extremally disconnected. Maximal tychonoffness of subspaces is also discussed.
متن کاملCountable Connected Spaces
Introduction, Let © be the class of all countable and connected perfectly separable Hausdorff spaces containing more than one point. I t is known that an ©-space cannot be regular or compact. Urysohn, using a complicated identification of points, has constructed the first example of an ©-space. Two ©-spaces, X and X*, more simply constructed and not involving identifications, are presented here...
متن کاملHomogeneous Countable Connected Hausdorff Spaces
In 1925, P. Urysohn gave an example of a countable connected Hausdorff space [4]. Other examples have been contributed by R. Bing [l], M. Brown [2], and E. Hewitt [3]. Relatively few of the properties of such spaces have been examined. In this paper the question of homogeneity is studied. Theorem I shows that there exists a bihomogeneous countable connected Hausdorff space. Theorems II and III ...
متن کاملPolitical Economists are Neither Selfish nor Indoctrinated
Most professional economists believe that economist in general are more selfish than other persons and that this greater selfishness is due to economic education. In this paper we offer empirical evidence against this widely held belief. Using a unique data set about giving behaviour to two social funds at the University of Zurich, it is shown that economic training does not make people act mor...
متن کاملNeither fragments nor ellipsis *
Jason Merchant (2004, and Chap. 3, this volume) proposes to account for all speech acts performed with “fragments,” whether in discourse-initial position or otherwise, by appealing to syntactic ellipsis. Though his proposal is insightful, I offer empirical and methodological considerations against it. Empirical problems include: (a) His alleged “elliptical sentences” do not embed the way they s...
