The Results of Our Project. thoralf skolem proved that n = 0,1 mod 4 was anecessary and sufficient condition for the existence of skolem sequences.
http://mathcs.mta.ca/research/cbaker/skolem/results.htm

Extractions: Thoralf Skolem proved that n 0,1 mod 4 was a necessary and sufficient condition for the existence of Skolem sequences. Similarly, we have proven that n 0,1 mod 4 is also a necessary and sufficient condition for the existence of Skolem arrays. Despite this, we have yet to find a direct link between Skolem sequences and Skolem arrays. Current research is devoted to finding a link between Skolem arrays and combinatorial designs. A split pair occurs when the two instances of a number appear on different rows. We conjecture that in all Skolem arrays, the number of split pairs is greater than or equal to the number of unsplit pairs.

Skolem's Paradox And The Predestination/Free-Will Discussion

Extractions: 4. Conclusions 0. Introduction How our disciplines illuminate our faith is an important consideration in the faith-learning discussion. I believe that it is more important than the reverse question if only because I regard my faith as ultimately more important than my discipline. I also think that the question of how the disciplines illuminate faith is the harder question. Our faith is a whole world-view, which can more naturally illumine all else. The purpose of this paper is to show that both sides of the predestination/freewill discussion are admissible in a way that is more profound than simply the wave-particle duality of light. In wave-particle duality there are two competing physical models of reality which are contradictory. I shall show below that not a contradiction but a difference in viewpoint is the fundamental issue in the discussion of predestination and free will. A discussion of Skolem's paradox is helpful in this demonstration. 1. The predestination/free-will discussion

Extractions: Skolemization Suppose we are given a proof task of the form A, ( X)( y)(W)B ] Q where A is some set of formulae, where W is some sequence of quantifiers, where B is a formula that does not begin with a quantifier, and where indicates that the signature involved is Then to achieve this proof task, it suffices to do the proof task A, ( X)(W)P' (y')] Q where ](y') indicates the signature formed from by adding a new function symbol y' , called a Skolem function , with arguments given by X , and where P' is P with each free instance of y replaced by y' This rule, called Skolemization (after the logician Thoralf Skolem) is justified in Chapter 8 of Theorem Proving and Algebra For example, given the proof task (where the variables range over integers) x)( y)(x + y = 0) ] Q . it suffices to prove x)(x + y'(x) = 0) (y')] Q . where y'(x) is the Skolem function (it is the negation function in this case). In many cases the Skolemized form is easier to use. This rule can be applied repeatedly to eliminate all existential quantifiers from formulae to the left of the symbol.

Extractions: model theory, Skolem paradox, Ramsey theorem, Loewenheim, categorical, Ramsey, Skolem, Gödel, completeness theorem, categoricity, Goedel, theorem, completeness, Godel Back to title page Some widespread Platonist superstitions were derived from other important results of mathematical logic (omitted in the main text of this book): Goedel's completeness theorem for predicate calculus, Loewenheim-Skolem theorem, the categoricity theorem of second order Peano axioms. In this short Appendix I will discuss these results and their methodological consequences (or lack of them). All these results have been obtained by means of the so-called model theory . This is a very specific approach to investigation of formal theories as mathematical objects. Model theory is using the full power of set theory. Its results and proofs can be formalized in ZFC. Model theory is investigation of formal theories in the metatheory ZFC. The main structures of model theory are interpretations .

Extractions: Here it is the succession of PhD advisers and students that goes backwards in time from my own degree. For the later entries it is not clear that there was a formal advisor/student/degree relationship, but there is evidence that one person was influenced in their education by the other. It seems odd that [TCSG] lists Ore as a student of Skolem, with Ore's degree awarded in 1924 while [BDM] lists Skolem's degree as being given in 1926. The following quotes are from articles in the Biographical Dictionary of Mathematicians [BDM]: Skolem: "In the latter year [1916] he returned to Oslo, where he was made Dozent in 1918. He received his doctorate in 1926." (H. Oettel, p. 2296) Thue: "Thue enrolled at Oslo University in 1883 and became a candidate for the doctorate in 1889." (Viggo Brun, p. 2460)
