Curve interpolation using algebraic hyperbolic Pythagorean Hodograph curves of order four(四阶代数双曲毕达哥拉斯速端曲线插值方法)

Zhejiang Daxue xuebao. Lixue ban
This paper investigates geometric interpolation methods using algebraic hyperbolic Pythagorean Hodograph (AHPH) curves of order four, including G1 Hermite interpolation, C1 Hermite interpolation, and planar three-points interpolation. PH curves have been

Canyon effects structure fin whale feeding aggregations at Southern Ocean feeding grounds

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Large fin whale feeding aggregations at Southern Ocean feeding grounds are one of the most striking predator–prey phenomena in the post‐whaling era, representing a visible sign of recovering large whale populations. Yet, the mechanisms shaping their occurrence have not yet been studied. We investigate spatial patterns of fin whale distribution

Interpolation remainder theory from taylor expansions with non-rectangular domains of influence

, 1972
Sobolev norm error bounds are derived for interpolation remainders on triangles using two types of Taylor expansion. These bounds are applied to the finite element analysis of Poisson's equation on a triangulation of a polygonal ...

Bivariate High-Accuracy Hermite-Type Multiquadric Quasi-Interpolation Operators

Journal of Mathematics
In this paper, a kind of Hermite-type multiquadric quasi-interpolation operator is constructed by combining an extended univariate multiquadric quasi-interpolation operator with a bivariate Hermite interpolation polynomial.

Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Scattered Hermite interpolation using radial basis functions

, 1994
We study the scattered Hermite interpolation problem and find several classes of radial basis functions, including the multiquadrics, which may be implemented for this interpolation ...

Weighted Lagrange and Hermite–Fejér interpolation on the real line

Journal of Inequalities and Applications, 1997
For a wide class of weights, a systematic investigation of the convergence-divergence behavior of Lagrange interpolation is initiated. A system of nodes with optimal Lebesgue constant is found, and for Hermite weights an exact lower estimate of the norm

On a Class of Hermite Interpolation Polynomials for Nonlinear Second Order Partial Differential Operators

EPJ Web of Conferences, 2018
This article is devoted to the problem of construction of Hermite interpolation formulas with knots of the second multiplicity for second order partial differential operators given in the space of continuously differentiable functions of two variables ...

Deforming the Double‐Scaled SYK and Reaching the Stretched Horizon From Finite Cutoff Holography

Fortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We study the properties of the double‐scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Dirichlet boundaries. The formalism immediately incorporates a lower‐dimensional analog of TT¯(+Λ2)$\text{T}\overline{\text{T}}(+\Lambda _2)$ deformations, denoted T2 ...

Piecewise rational quadratic interpolation to monotonic data

, 1981
An explicit representation of a piecewise rational quadratic function is developed which produces a monotonic interpolant to given monotonic data. The explicit representation means that the piecewise monotonic interpolant is easily constructed and ...
