On certain localized version of uniform selection principles

نویسندگان

چکیده

We intend to localize the selection principles in uniform spaces (Ko\v{c}inac, 2003) by introducing their local variations, namely locally $\Upsilon$-bounded (where $\Upsilon$ is Menger, Hurewicz or Rothberger). It has been observed that difference between and corresponding correlatives as introduced here reasonable enough discuss about these new notions. Certain observations using critical cardinals (on which have not studied before) well preservation like properties versions) are presented. The interrelationships notions considered this paper outlined into an implication diagram. interactions variations also investigated. present several examples illustrate distinguishable behaviour of

On certain maximality principles

‎We present streamlined proofs of certain maximality principles studied by Hamkins‎ ‎and Woodin‎. ‎Moreover‎, ‎we formulate an intermediate maximality principle‎, ‎which is‎ ‎shown here to be equiconsistent with the existence of a weakly compact cardinal $kappa$ such that $V_{kappa}prec V$‎.

A Certain Version of Preservationism

A certain approach to paraconsistency was initiated by works of R. Jennings and P. Schotch. In their “Inference and necessity” [4] they proposed a notion of a level of inconsistency (incoherence) of a given set of premises. This level is a measure that assigns to a given set of premises X, the least number of elements of covers of X that consist of consistent subsets of X. The idea of the level...

Certain Principles of Biomorphic Robots

Figure 1. Biped used in the visual control of gait experiments. Abstract-The field of biomorphic robotics can advance as quickly as clear principles of biological systems can be identified, implemented, and tested in robotic devices. Here, we describe the implementation of three principles: (1) The prediction of the sensory consequences of movement and its role in the extraction of novelty and ...

Examining the difficulty pathways of can-do statements from a localized version of the CEFR

The Japanese adaptation of the Common European Framework of Reference (CEFR-J) is a tailored version of the Common European Framework of Reference (CEFR), designed to better meet the needs of Japanese learners of English. The CEFR-J, like the CEFR, uses illustrative  descriptors  known  as  can-do  statements,  that  describe  achievement  goals  for five  skills  (listening,  reading,  spoken ...
