Inverse problems for semilinear elliptic PDE with a general nonlinearity a(x,u)$a(x,u)$
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract This article studies the inverse problem of recovering a nonlinearity in an elliptic equation Δu+a(x,u)=0$\Delta u + a(x,u) = 0$ from boundary measurements of solutions. Previous results based on first‐order linearization achieve this under a sign condition on ∂ua(x,u)$\partial _u a(x,u)$, and results based on higher order linearization ...

A non-linear differential equation and a Fredholm determinant
, 1992 In several branches of mathematical physics one comes across the Fredholm determinant of the kernel $\sin (x-y)\pi/(x-y)\pi$ on the finite interval ($-t,t$). Jimbo, Miwa, Mori and Sato derived a non-linear differential equation for it.

Replica Bethe Ansatz solution to the Kardar-Parisi-Zhang equation on the half-line
SciPost Physics, 2020 We consider the Kardar-Parisi-Zhang (KPZ) equation for the stochastic growth of an interface of height $h(x,t)$ on the positive half line with boundary condition $\partial_x h(x,t)|_{x=0}=A$.

Exact WKB methods in SU(2) Nf = 1
Journal of High Energy Physics, 2022 We study in detail the Schrödinger equation corresponding to the four dimensional SU(2) N $$ \mathcal{N} $$ = 2 SQCD theory with one flavour. We calculate the Voros symbols, or quantum periods, in four different ways: Borel summation of the WKB series ...

Animal Genetics, Volume 57, Issue 5, October 2026.ABSTRACT A previous genome‐wide association study identified regions on canine chromosome (cfa) 13 and 14 associated with early onset myxomatous mitral valve disease (MMVD) in Cavalier King Charles Spaniels (CKCS). In the present study, whole genome sequencing (WGS) of 9 CKCS cases (mitral regurgitation (MR) before 4.5 years or congestive heart failure

Strong coupling expansion in 𝒩 = 2 superconformal theories and the Bessel kernel
Journal of High Energy Physics, 2022 We consider strong ’t Hooft coupling expansion in special four-dimensional 𝒩 = 2 superconformal models that are planar-equivalent to 𝒩 = 4 super Yang-Mills theory.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer
Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Painlevé tau-functions and Fredholm determinants [PDF]
, 2021 It is now known that the tau-functions associated to the generic solutions of the Painlevé equations III, V, VI can be expressed as a Fredholm determinants. The minor expansion of these determinants provide an interesting connection to random partitions.

Complex eigenvalue instantons and the Fredholm determinant expansion in the Gross-Witten-Wadia model
Journal of High Energy PhysicsWe study the leading nonperturbative corrections to the strong-coupling (ungapped) phase of the Gross-Witten-Wadia (GWW) integral over unitary matrices, to one-loop order.
