A Weierstrass-type representation for Lagrangian surfaces in R^4
, 2000 International audienceWe derive a Weierstrass-type formula for conformal Lagrangian immersions in complex Euclidean 2-space, and show that the data satisfies a Dirac-type equation with complex potential.

Isometric immersions into three‐dimensional unimodular metric Lie groups
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.

On the Dynamics and Stability of a Pendulum With Lateral Springs
Journal of MathematicsThis study characterizes the conservative dynamics of a simple pendulum interacting laterally with a pair of ideal springs—a configuration in which gravitational and elastic restoring forces manifest through nonlinear trigonometric geometry.

Equidistribution in 2‐nilpotent Polish groups and triple restricted sumsets
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract The aim of this paper is to establish a Ratner‐type equidistribution theorem for orbits on homogeneous spaces associated with 2$\hskip.001pt 2$‐nilpotent locally compact Polish groups under the action of a countable discrete abelian group.

Equivariant spaces of matrices of constant corank one
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We classify all irreducible G$G$‐equivariant subspaces of Hom(V1,V2)$\operatorname{Hom}(V_1,V_2)$ of constant corank one, where G$G$ is a reductive group over an algebraically closed field of characteristic zero and Vi$V_i$ are irreducible representations.

Weierstrass per ell mateix: alguns trets del seu pensament matemàtic [PDF]
, 2015 La coneixença de Karl Weierstrass (1815-1897) a través dels teoremes que s’estudien a matemàtiques ens aporta una visió parcial del personatge. En aquesta xerrada pretenem enriquir aquesta visió apropant-nos tant a l’home com al matemàtic, des d’un ...

Diverse Soliton Structures of Induced Curves in the Integrable Coupled Kuralay Equation
Advances in Mathematical PhysicsThis study explores the integrable coupled Kuralay equation, which is widely utilized to study the motion of induced curves. In fields such as ferromagnetic materials, nonlinear optics, and optical fibers, soliton solutions of the Kuralay equation have ...

Weierstrass-type representations for timelike surfaces
Advanced Studies in Pure Mathematics, 2018 In this paper we give the Weierstrass-type representation for Lorentz conformal minimal surfaces in Minkowski 3-space that was derived by Konderak, and a new one for Lorentz conformal constant mean curvature 1 surfaces in anti de Sitter 3-space, using integrable systems techniques. As an application, we analyze their singularities. Finally, we describe
