    • Algebraic equations for constant width curves and Zindler curves 

      Rochera, D.Autoridad BCAM (2022-03)
      An explicit method to compute algebraic equations of curves of constant width and Zindler curves generated by a family of middle hedgehogs is given thanks to a property of Chebyshev polynomials. This extends the methodology ...
    • Offsets and front tire tracks to projective hedgehogs 

      Rochera, D.Autoridad BCAM (2022-07-25)
      There are some known properties on curves of constant width and Zindler curves and their relationship with offsets and front tire-track curves in convex geometry. In this work, a generalization of all these concepts and ...
    • On isoptics and isochordal-viewed curves 

      Rochera, D.Autoridad BCAM (2021)
      In this paper, some results involving isoptic curves and constant $\phi$-width curves are given for any closed curve. The non-convex case, as well as non-simple shapes with or without cusps are considered. Relating the ...
    • Regular polygons on isochordal-viewed hedgehogs 

      Rochera, D.Autoridad BCAM (2022)
      A curve $\alpha$ is called isochordal viewed if there is a smooth motion of a constant length chord with its endpoints along $\alpha$ such that their tangents to the curve at these points form a constant angle. In this ...
