Independence and abstract multiplication ∗
نویسندگان
چکیده
We investigate the notion of independence, which is at the basis of many, seemingly unrelated, properties of logics, like the Rational Monotony rule of nonmonotonic logics, but also of interpolation theorems of monotonic and nonmonotonic logic. We show a strong connection between independence and certain rules about multiplication of abstract size in the field of nonmonotonic logic. We think that this notion of independence, with its ramifications, is extremely important, and has not been sufficiently investigated.

متن کاملSome Preliminary Results about Uncertain Matrix
Correspondence: [email protected]; http://orsc.edu.cn/liu Department of Mathematical Sciences, Tsinghua University, Beijing 100084, China Abstract This paper presents a new concept of uncertain matrix that is a measurable function from an uncertainty space to the set of real matrices. It is proved that an uncertain matrix is a matrix all of whose elements are uncertain variables. The independ...
متن کاملLogic Operators on Delta-Sigma Bit-Streams
Abstract: The fundamental logic operations NOT, OR, AND, and XOR processing bit-streams of ∆Σ-modulators are discussed herein. The resulting bit-streams are evaluated on the basis of their mean values and their standard deviations. Mathematical expressions are presented for their mean values; i.e., the logic function XOR results in the negative multiplication of two bipolar bit-streams, and the...
متن کاملA generalisation of independence in statistical models for categorical distribution
Abstract: In this paper, generalised statistical independence in statistical models for categorical distributions is proposed from the viewpoint of generalised multiplication characterised by a monotonically increasing function and its inverse function, and it is implemented in naive Bayes models. This paper also proposes an idea of their estimation method which directly uses empirical marginal...
متن کاملPeriods of Third Kind for Rank 2 Drinfeld Modules and Algebraic Independence of Logarithms
In analogy with the periods of abelian integrals of differentials of third kind for an elliptic curve defined over a number field, we introduce a notion of periods of third kind for a rank 2 Drinfeld Fq[t]-module ρ defined over an algebraic function field and derive explicit formulae for them. When ρ has complex multiplication by a separable extension, we prove the algebraic independence of ρlo...
