Periodic dynamic systems for infected hosts and mosquitoes

Revista de Saúde Pública, 1996
A mathematical model for the purpose of analysing the dynamic of the populations of infected hosts anf infected mosquitoes when the populations of mosquitoes are periodic in time is here presented.

Nested algebraic Bethe ansatz for orthogonal and symplectic open spin chains

Nuclear Physics B, 2020
We present a nested algebraic Bethe ansatz for one-dimensional so2n- and sp2n-symmetric open spin chains with diagonal boundary conditions. The monodromy matrix of these spin chains satisfies the defining relations on the extended twisted Yangians Xρ ...

Multiple front and pulse solutions in spatially periodic systems

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

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].

Limits of cubic differentials and buildings

Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract In the Labourie–Loftin parameterization of the Hitchin component of surface group representations into SL(3,R)$\mathrm{SL}(3,\mathbb {R})$, we prove an asymptotic formula for holonomy along rays in terms of local invariants of the holomorphic differential defining that ray.

A general order full-discretization algorithm for chatter avoidance in milling

Advances in Mechanical Engineering, 2018
Based on the full-discretization method, this work presents a generalized monodromy matrix as an exact function of the order of polynomial approximation of the milling state for chatter avoidance algorithm.

Infinite distances in field space and massless towers of states

Journal of High Energy Physics, 2018
It has been conjectured that in theories consistent with quantum gravity infinite distances in field space coincide with an infinite tower of states becoming massless exponentially fast in the proper field distance.

Riemann-Hilbert problems, Toeplitz operators and ergosurfaces

Journal of High Energy Physics
The 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 ...

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.
