The Jacobian conjecture for symmetric Jacobian matrices
Journal of Pure and Applied Algebra, 2004 Let \(F = (F_1,\ldots,F_n) : \mathbb C^n \longrightarrow \mathbb C^n\) be a polynomial map and \(J(F) = (\partial F_i/\partial x_j)\) the Jacobian matrix of \(F\). The Jacobian conjecture asserts that \(F\) is invertible if det\((J(F)) \in \mathbb C^*\).

Per-unit Scheme for Integrated Solution of Hybrid Power-water Flow Problem
Journal of Modern Power Systems and Clean Energy, 2023 When applying the widely-used Newton-Raphson (N-R) method to the integrated solution of the hybrid power-water flow problem of the power-water integrated energy system (PW-IES), it is found that there are numerical differences among Jacobian elements ...

Study of the Jacobian of an extended Kalman filter for soil analysis in SURFEXv5 [PDF]
Geoscientific Model Development, 2015 An externalised surface scheme like SURFEX allows computationally cheap offline runs. This is a major advantage for surface assimilation techniques such as the extended Kalman filter (EKF), where the offline runs allow a cheaper numerical ...

The universal tropical Jacobian and the skeleton of the Esteves' universal Jacobian [PDF]
Proceedings of the London Mathematical Society, 2018 For each universal genus‐ g polarization μ of degree d , we construct a universal tropical Jacobian Jμ,gtrop as a generalized cone complex over the moduli space of stable pointed genus‐ g tropical curves. We show several properties of the space Jμ,gtrop .

The monodromy pairing and discrete logarithm on the Jacobian of finite graphs
Journal of Mathematical Cryptology, 2010 Every graph has a canonical finite abelian group attached to it. This group has appeared in the literature under a variety of names including the sandpile group, critical group, Jacobian group, and Picard group.

On the Kinematics of Robotic-assisted Minimally Invasive Surgery [PDF]
Modeling, Identification and Control, 2013 Minimally invasive surgery is characterized by the insertion of the surgical instruments into the human body through small insertion points called trocars, as opposed to open surgery which requires substantial cutting of skin and tissue to give the ...
