Antonio Algaba Duran

Antonio Algaba Duran is a Professor at the Higher Technical School of Engineering within the University of Seville, specializing in Applied Mathematics at the Center for Advanced Studies in Physics, Mathematics, and Computing. His research focuses on dynamical systems, nonlinear differential equations, and bifurcation theory, with significant contributions to the analysis of nilpotent singularities, homoclinic/heteroclinic orbits, and chaotic behavior in systems like the Lorenz, Chen, and Lü systems.

• Education: PhD from University of Seville (1996), thesis on Hypernormal forms and bifurcations in flat and three-dimensional systems, supervised by Emilio Freire Macías and Estanislao Gamero Gutiérrez.
• Research Highlights:
  • 131+ publications since 1998, including 2 preprints
  • Developed algorithms for normal forms and nonlinear time transformations to analyze canard explosions and homoclinic bifurcations
  • Key work on Z2-symmetric systems, inverse integrating factors, and geometric criteria for centers
• Collaborators: Cristóbal García, Alejandro J. Rodríguez-Luis, Manuel Merino, Estanislao Gamero, and others.

His scientific work spans applications in electronic circuits, biological systems, and physical models, with a focus on structural stability, analytic integrability, and global bifurcations.
