Some remarks on cardinal arithmetic without choice
One important consequence of the Axiom of Choice is the absorption law of cardinal arithmetic. It states that for any cardinals m and n, if m 6 n and n is infinite, then m+ n = n and if m 6= 0, m · n = n. In this paper, we investigate some conditions that make this property hold as well as an instance when such a property cannot be proved in the absence of the Axiom of Choice. We further find s...
متن کاملSome remarks on choice functions and LF-movement
The discussion is indebted very much to the lucid representation given in Heim (1994) which, in several respects, is more elaborate than the account given here. Furthermore, I wish to thank Graham Katz, Manfred Kup er, Cecile Meier and Wolfgang Sternefeld for discussion and help. The article has pro ted enormously by the comments of two anonymous referees and several detailed suggestions by Kla...
متن کاملSome Remarks on Choice Functions and Lf-movement
It is well known that indefinite phrases are more liberal in taking scope than other quantifying phrases. In general, the scope of indefinites is not limited by the finite clause in which they occur, although the scope of universal quantifiers is. Wh-phrases behave very much like indefinites: in languages with wh in situ, their scope need not be restricted by anything like clause boundedness. I...
متن کاملAutomated Reasoning in Social Choice Theory: Some Remarks
Our objective in this note is to comment briefly on the newly emerging literature on computer-aided proofs in Social Choice Theory. We shall specifically comment on [16] (henceforth TL) and [4] (henceforth GE). In the Appendix we provide statements and brief descriptions of the results discussed in this note.

متن کاملRemarks on microperiodic multifunctions
It is well known that a microperiodic function mapping a topological group into reals, which is continuous at some point is constant. We introduce the notion of a microperiodic multifunction, defined on a topological group with values in a metric space, and study regularity conditions implying an analogous result. We deal with Vietoris and Hausdorff continuity concepts.Stability of microperiodi...
