An upper bound for validity limits of asymptotic analytical approaches based on normal form theory [PDF]

open access: yes, 2012
Perturbation methods are routinely used in all fields of applied mathematics where analytical solutions for nonlinear dynamical systems are searched.

Analytical Solution to Normal Forms of Hamiltonian Systems

open access: yesMathematical and Computational Applications, 2017
The idea of the normalisation of the Hamiltonian system is to simplify the system by transforming Hamiltonian canonically to an easy system. It is under symplectic conditions that the Hamiltonian is preserved under a specific transformation—the so-called

Design system for normalization by Using Normal Forms

open access: yesTikrit Journal of Pure Science, 2023
Electronic learning is the use of modern technology of different  types for information delivery in order to reduce both time and effort for maintaining a wide range of benefit through many patterns or programs like simulation which help the learner to ...

Disjunctive bases: normal forms and model theory for modal logics [PDF]

open access: yesLogical Methods in Computer Science, 2022
We present the concept of a disjunctive basis as a generic framework for normal forms in modal logic based on coalgebra. Disjunctive bases were defined in previous work on completeness for modal fixpoint logics, where they played a central role in the ...

Gauss-Manin Connections for Boundary Singularities and Isochore Deformations

open access: yesDemonstratio Mathematica, 2015
We study here the relative cohomology and the Gauss-Manin connections associated to an isolated singularity of a function on a manifold with boundary, i.e. with a fixed hyperplane section.

Normal forms for reduced stochastic climate models. [PDF]

open access: yesProc Natl Acad Sci U S A, 2009
The systematic development of reduced low-dimensional stochastic climate models from observations or comprehensive highdimensional climate models is an important topic for atmospheric low-frequency variability, climate sensitivity, and improved extended ...

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].

Reversible-equivariant systems and matricial equations

open access: yesAnais da Academia Brasileira de Ciências, 2011
This paper uses tools in group theory and symbolic computing to classify the representations of finite groups with order lower than, or equal to 9 that can be derived from the study of local reversible-equivariant vector fields in 4 .

Probabilistic Rewriting and Asymptotic Behaviour: on Termination and Unique Normal Forms [PDF]

open access: yesLogical Methods in Computer Science, 2022
While a mature body of work supports the study of rewriting systems, abstract tools for Probabilistic Rewriting are still limited. In this paper we study the question of uniqueness of the result (unique limit distribution), and develop a set of proof ...
