Special Issue Information

Dear Colleagues,

We are pleased to announce the Special Issue entitled “Theory of Curves and Knots with Applications” to be published in the journal Axioms.

Curves are the fundamental geometric elements that have a deep history and still represent an area of intense research activity. Theory of curves can be studied from various aspects and serves as a bridge between different mathematical disciplines. Knot theory is concerned with the study of mathematical knots that represent closed curves without self-intersections. The beauty and depth of curves and knots extend beyond pure mathematics, finding applications in areas such as molecular biology and quantum physics.

This Special Issue is devoted to both the foundational concepts of curves and knots as well as its newer, multidisciplinary applications in various fields of study.

The topics covered in this Special Issue include, but are not limited to the following:

  • Various aspects of the theory of curves: differential geometry of curves, topological aspects, algebraic curves, analytic curves, curves on the surfaces, curve deformation, curves in Minkowski space, curves on manifolds, magnetic curves, geodesics, dual curves in dual spaces, fractal curves, etc;
  • Traditional aspects of knot theory: knot invariants, knot polynomials, and braids. Connections with low-dimensional topology, 3-manifolds and higher dimension spaces, algebraic structures, geometry, and combinatorics;
  • Interdisciplinary applications of curves and knots in fields outside of pure mathematics like molecular biology (e.g., DNA knotting and unknotting), physics (e.g., quantum mechanics, statistical mechanics, kinematics), computer science (e.g., algorithms for knot recognition and classification, computer graphics and design), architecture (curved structures and their stability), engineering, etc.

The purpose of this Special Issue is to present the latest research findings in curves and knots, to highlight the diverse applications and to provide a platform for researchers to share knowledge, collaborate, and advance the study and applications of curve and knot theory.

This Special Issue will serve as a contribution to existing literature by bringing together interdisciplinary research that showcases the breadth of applications of curves and knots.

Spectral curves are algebraic curves associated to commutative subalgebras of rings of ordinary differential operators (ODOs). Their origin is linked to the Korteweg–de Vries equation and to seminal works on commuting ODOs by I. Schur and Burchnall and Chaundy. They allow the solvability of the spectral problem Ly=λy, for an algebraic parameter λ and an algebro-geometric ODO L, whose centralizer is known to be the affine ring of an abstract spectral curve Γ. In this work, we use differential resultants to effectively compute the defining ideal of the spectral curve Γ, defined by the centralizer of a third-order differential operator L, with coefficients in an arbitrary differential field of zero characteristic. For this purpose, defining ideals of planar spectral curves associated to commuting pairs are described as radicals of differential elimination ideals. In general, Γ is a non-planar space curve and we provide the first explicit example. As a consequence, the computation of a first-order right factor of Lλ becomes explicit over a new coefficient field containing Γ. Our results establish a new framework appropriate to develop a Picard–Vessiot theory for spectral problems. Full article
