Monodromy Matrix for Linear Difference Operators with Almost Constant Coefficients
Journal of Mathematical Analysis and Applications, 1995 Abstract: "A new method is proposed for solving the discrete scattering problem for a linear single-valued difference operator of arbitrary order with almost constant coefficients. The treatment is concerned with the asymptotic behavior of its eigenfunctions as [absolute value of t] -> [infinity].

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract Twistor spaces are certain compact complex three‐folds with an additional real fibre bundle structure. We focus here on twistor spaces over P2#P2#P2${\mathbb {P}}^2\#{\mathbb {P}}^2\#{\mathbb {P}}^2$. Such spaces are either small resolutions of double solids or they can be described as modifications of conic bundles.

The cosymplectic Chern–Hamilton conjecture
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract In this paper, we study the Chern–Hamilton energy functional on compact cosymplectic manifolds, fully classifying in dimension 3 those manifolds admitting a critical compatible metric for this functional. This is the case if and only if either the manifold is co‐Kähler or if it is a mapping torus of the 2‐torus by a hyperbolic toral ...

Riemann-Hilbert problems, Toeplitz operators and ergosurfaces
Journal of High Energy PhysicsThe Riemann-Hilbert approach, in conjunction with the canonical Wiener-Hopf factorisation of certain matrix functions called monodromy matrices, enables one to obtain explicit solutions to the non-linear field equations of some gravitational theories ...

Monodromy of the quantum 1:1:2 resonant swing spring
, 2004 We describe the qualitative features of the joint spectrum of the quantum 1:1:2 resonant swing spring. The monodromy of the classical analogue of this problem is studied in Dullin et al. [Physica D 190, 15–37 (2004)].

Universal character, phase model and topological strings on $$\pmb {\mathbb {C}^3}$$ C3
European Physical Journal C: Particles and Fields, 2019 In this paper, we consider two different subjects: the algebra of universal characters $$S_{[\lambda ,\mu ]}(\mathbf{x},\mathbf{y})$$ S[λ,μ](x,y) (a generalization of Schur functions) and the phase model of strongly correlated bosons.

New symmetries of $\mathfrak{gl}(N)$-invariant Bethe vectors
, 2019 International audienceWe consider quantum integrable models solvable by the nested algebraic Bethe ansatz and possessing -invariant R-matrix. We study two types of Bethe vectors. The first type corresponds to the original monodromy matrix.
