Gronwall-type integral inequalities with impulses on time scales
Advances in Difference Equations, 2011 In this article, some Gronwall-type integral inequalities with impulses on time scales are investigated. Our results extend some known dynamic inequalities on time scales, unify and extend some continuous inequalities and their corresponding discrete ...

Rapid evolution of complex limit cycles [PDF]
, 2009 The current article studies certain problems related to complex cycles of holomorphic foliations with singularities in the complex plane. We focus on the case when polynomial differential one-form gives rise to a foliation by Riemann surfaces.

ARMAX(p,r,q) parameter identifiability without coprimeness [PDF]
, 2012 In the ARMAX(p; r; q) model given (p; r; q); the presence of multiple parameters is often ignored. In a coprime model Hannan has shown that the unrestricted reduced form (URF) parameter is identifiable under the simple condition that the end parameter ...

On the lifting and reconstruction of nonlinear systems with multiple attractors
, 2023 The Koopman operator provides a linear perspective on non-linear dynamics by focusing on the evolution of observables in an invariant subspace. Observables of interest are typically linearly reconstructed from the Koopman eigenfunctions.

Nonlinear Cointegration and Nonlinear Error Correction: Record Counting Cointegration Tests. [PDF]
In this article we propose a record counting cointegration (RCC) test that is robust to nonlinearities and certain types of structural breaks. The RCC test is based on the synchronicity property of the jumps (new records) of cointegrated series, counting
