Apparent horizons in the quasispherical Szekeres models
The notion of an apparent horizon (AH) in a collapsing object can be carried over from the Lemaı̂treTolman to the quasispherical Szekeres models in three ways: 1. Literally by the definition—the AH is the boundary of the region, in which every bundle of null geodesics has negative expansion scalar. 2. As the locus, at which null lines that are as nearly radial as possible are turned toward decre...
متن کاملThe Szekeres Multidimensional Continued Fraction
In his paper "Multidimensional continued fractions" {Ann. Univ. Sei. Budapest. EOtvOs Sect. Math., y. 13, 1970, pp. 113-140), G. Szekeres introduced a new higher dimensional analogue of the ordinary continued fraction expansion of a single real number. The Szekeres algorithm associates with each fc-tuple (a»,..., ak) of real numbers (satisfying 0 < a< 1) a sequence bx, b2,... of positive intege...

If he is in the upper 10 per cent of his class at school, it might be well to advance him to the next grade, provided he is sufficiently interested to show that he is capable of doing the work. If convenient, the teacher should...
متن کاملGeorge Kachergis: George Kachergis Doctoral Dissertation
Language acquisition is a ubiquitous, challenging problem involving fundamental cognitive abilities of attention, learning, and memory. From infants to adult travelers, language learners are faced with figuring out which words refer to which referents from situations that contain many words and referents. By remembering the words and referents (e.g., objects) that co-occur most frequently over ...
متن کاملOn a Paper of Erdös and Szekeres
Propositions 1.1 – 1.3 stated below contribute to results and certain problems considered in [E-S], on the behavior of products ∏n 1 (1 − zj), 1 ≤ a1 ≤ · · · ≤ an integers. In the discussion below, {a1, . . . , an} will be either a proportional subset of {1, . . . , n} or a set of large arithmetic diameter.
