Normal forms for symplectic matrices [PDF]

open access: yesPortugaliae Mathematica, 2014
We give a self contained and elementary description of normal forms for symplectic matrices, based on geometrical considerations. The normal forms in question are expressed in terms of elementary Jordan matrices and integers with values in \{ -1,0,1\}

FURTHER REDUCTION OF NORMAL FORMS AND UNIQUE NORMAL FORMS OF SMOOTH MAPS

open access: yesInternational Journal of Bifurcation and Chaos, 2008
Further reduction for classical normal forms of smooth maps is considered in this paper. Firstly, based on the idea of computation of simplest normal forms for vector fields [Yu & Yuan, 2003], we compute the transformed map of a given smooth map under a near identity formal transformation, and give a recursive formula for the homogeneous terms of ...

Normal Forms of Conditional Belief Bases Respecting Inductive Inference

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2022
Normal forms of syntactic entities play an important role in many different areas in computer science. In this paper, we address the question of how to obtain normal forms and minimal normal forms of conditional belief bases in order to, e.g., ease ...

Unique normal forms near a degenerate elliptic fixed point in two-parametric families of area-preserving maps [PDF]

open access: yes, 2014
We derive simplified normal forms for an area-preserving map in a neighbourhood of a degenerate resonant elliptic fixed point. Such fixed points appear in generic families of area-preserving maps. We also derive a simplified normal form for a generic two-

A normal form for spider diagrams of order [PDF]

open access: yes, 2014
We develop a reasoning system for an Euler diagram based visual logic, called spider diagrams of order. We de- fine a normal form for spider diagrams of order and provide an algorithm, based on the reasoning system, for producing diagrams in our normal ...

Representation of logic formulas by normal forms [PDF]

open access: yes, 1996
summary:In this paper, we deal with the disjunctive and conjunctive normal forms in the frame of predicate BL-logic and prove theirs conditional equivalence to appropriate formulas. Our aim is to show approximation ability of special normal forms defined

Normal Form Nested Programs [PDF]

open access: yesFundamenta Informaticae, 2008
Disjunctive logic programming under the answer set semantics (DLP, ASP) has been acknowledged as a versatile formalism for knowledge representation and reasoning during the last decades. Lifschitz, Tang, and Turner have introduced an extended language of DLP, called Nested Logic Programming (NLP), in 1999 [12].
