Unification By Induction
نویسنده
چکیده
We show that the problem of unifying electromagnetism with gravity has an elegant solution in classical physics through the phenomenon of induction. By studying the way that induction leads to the formation of electromagnetic fields, we identify the classical field equations which the unified field must satisfy and a corresponding set of constitutive equations for the medium sustaining the field. The unification problem is then reduced to the problem of finding the exact form of these constitutive equations for different media by experiments.

The Effects of Exchange Rate Unification on the Iranian Economy
The exchange rate unification is one of the most important instruments of economic adjustment, which is used in many countries. This paper shows the effects of the exchange rate unification on price level (inflation), gross domestic production (GDP), non-oil exports, private conception, government expenditure and stock of money. The data, is used related to the period 1959-2000. To analyze the ...

متن کاملLambda Unification
We give a formal description of an algorithm for lambda unification. The input to the algorithm consists of two terms t and s of lambda logic. The purpose of the algorithm is to find (sometimes) a substitution σ such that tσ = sσ is provable in lambda logic. In general such unifiers are not unique. Lambda logic itself is defined in [2]. We prove some basic metatheorems about lambda unification,...
متن کاملImplementing Anti-Unification Modulo Equational Theory
We present an implementation of E–anti–unification as defined in [Hei95], where tree–grammar descriptions of equivalence classes of terms are used to compute generalizations modulo equational theories. We discuss several improvements, including an efficient implementation of variable–restricted E–anti–unification from [Hei95], and give some runtime figures about them. We present applications in...
متن کاملA Machine-Checked Model of MGU Axioms: Applications of Finite Maps and Functional Induction
The most general unifier (MGU) of a pair of terms can be specified by four axioms. In this paper we generalize the standard presentation of the axioms to specify the MGU of a list of equational constraints and we formally verify that the unification algorithm satisfies the axioms. Our constraints are equalities between terms in a language of simple types. We model substitutions as finite maps f...
