, 2015 Basing on a modification of the "Dichotomy Algorithm" (Terekhov, 2010), we propose a parallel procedure for solving tridiagonal systems of equations with Toeplitz matrices.

Bayesian trans‐dimensional soil behaviour type inference using conditional posterior proposals
Geophysical Prospecting, Volume 73, Issue 5, Page 1510-1533, June 2025.ABSTRACT Identification of subsurface geological profiles is indispensable to geotechnical design and construction. Subsurface stratification through Bayesian inversion of soil behaviour type index data, obtained from cone penetration tests, is achieved through the development of a novel three‐block Markov chain Monte Carlo algorithm.

Constraining Kilometer‐Scale Mountain Snow Transport and Snowshed Areas
Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.Abstract Snow transport (wind drifting and avalanches) can concentrate a large amount of water into a relatively small area, in contrast to precipitation, which is spatially smoother. I develop a framework to constrain the minimum effective seasonal transport necessary to explain observed snowpack patterns.

Inversion of general tridiagonal matrices
Applied Mathematics Letters, 2006 AbstractIn the current work, the authors present a symbolic algorithm for finding the inverse of any general nonsingular tridiagonal matrix. The algorithm is mainly based on the work presented in [Y. Huang, W.F. McColl, Analytic inversion of general tridiagonal matrices, J. Phys. A 30 (1997) 7919–7933] and [M.E.A.

, 2014 We develop an equivalence between two Hilbert spaces: (i) the space of states of $U(1)^n$ Chern-Simons theory with a certain class of tridiagonal matrices of coupling constants (with corners) on $T^2$; and (ii) the space of ground states of strings on an

Formulation and Calibration of CATKE, a One‐Equation Parameterization for Microscale Ocean Mixing
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.Abstract We describe CATKE, a parameterization for fluxes associated with small‐scale or “microscale” ocean turbulent mixing on scales between 1 and 100 m. CATKE uses a downgradient formulation that depends on a prognostic turbulent kinetic energy (TKE) variable and a diagnostic mixing length scale that includes a dynamic convective adjustment (CA ...

Radio Science, Volume 60, Issue 3, March 2025.Abstract The generalized force method, previously developed for an isotropic inhomogeneous ionosphere, exploits the knowledge about the character of the extrema of the phase distance—where high ionospheric rays correspond to minima and low rays to saddle points—to systematically find all relevant rays between fixed points, thereby enabling efficient ...

The Darboux transformation and the complex Toda lattice [PDF]
, 2008 It is well known that each solution of the Toda lattice can be represented by a tridiagonal matrix J(t). Under certain restrictions, it is possible to obtain some new solution by using the Darboux transformation of J(t) ¡ CI. Our goal is the extension of

Global algorithms for maximal eigenpair
, 2017 This paper is a continuation of \ct{cmf16} where an efficient algorithm for computing the maximal eigenpair was introduced first for tridiagonal matrices and then extended to the irreducible matrices with nonnegative off-diagonal elements.
