Linear Hamiltonian behaviors and bilinear differential forms [PDF]
We study linear Hamiltonian systems using bilinear and quadratic differential forms. Such a representation-free approach allows us to use the same concepts and techniques to deal with systems isolated from their environment and with systems subject to ...

Classes of weak Dembowski–Ostrom polynomials for multivariate quadratic cryptosystems
T. Harayama and D. K. Friesen [J. Math. Cryptol. 1 (2007), 79–104] proposed the linearized binomial attack for multivariate quadratic cryptosystems and introduced weak Dembowski–Ostrom (DO) polynomials in this framework over the finite field 𝔽2.

Application of the Quasilinearization Method to Approximate Non-linear Delay Differential Equations in Physical Problems [PDF]
This paper investigates the application of the Quasilinearization Method (QLM) for approximating non-linear delay differential equations (DDEs), which are prevalent in fields such as control systems and population dynamics.

Geometry and integrability of quadratic systems with invariant hyperbolas
Let QSH be the family of non-degenerate planar quadratic differential systems possessing an invariant hyperbola. We study this class from the viewpoint of integrability.

Linear Systems of Real Quadratic Forms [PDF]
1. It is natural to consider invariantive properties of k-dimensional linear systems of real quadratic forms over Rn (or quadratic forms over Rn with values in RkI 2< k5 In(n + 1)), because of the occurrence of such objects at least in the following contexts: in the second fundamental form of classical differential geometry for n-dimensional manifolds ...

The Moduli Spaces of Parabolic Connections with a Quadratic Differential and Isomonodromic Deformations [PDF]
In this paper, we study the moduli spaces of parabolic connections with a quadratic differential. We endow these moduli spaces with symplectic structures by using the fundamental 2-forms on the moduli spaces of parabolic connections (which are phase ...
