Homogeneous Models of Nonlinear Circuits
Ricardo Riaza
This paper develops a general approach to nonlinear circuit modelling aimed at preserving the intrinsic symmetry of electrical circuits when formulating reduced models. The goal is…
Associate submersions and qualitative properties of nonlinear circuits with implicit characteristics
Ricardo Riaza
We introduce in this paper an equivalence notion for submersions , open in , which makes it possible to identify a smooth planar curve with a unique class of su…
Circuit theory in projective space and homogeneous circuit models
Ricardo Riaza
This paper presents a general framework for linear circuit analysis based on elementary aspects of projective geometry. We use a flexible approach in which no a priori assignment o…
Transcritical bifurcation without parameters in memristive circuits
Ricardo Riaza
The transcritical bifurcation without parameters (TBWP) describes a stability change along a line of equilibria, resulting from the loss of normal hyperbolicity at a given point of…
