Single-Stage Causal Incentive Design via Optimal Interventions
EntropyWe introduce Causal Incentive Design (CID), a framework that applies causal inference to canonical single-stage principal–agent problems (PAPs) characterized by bilateral private information.

Detecting When One Probe Vector is Enough for Preconditioned Log‐Determinant Approximation
Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.ABSTRACT We present randomized algorithms for estimating the log‐determinant of regularized symmetric positive semi‐definite matrices. The algorithms access the matrix only through matrix vector products, and are based on the introduction of a preconditioner and stochastic trace estimator.

Numerical Methods for Partial Differential Equations, Volume 42, Issue 4, July 2026.ABSTRACT The main purpose of this paper is to design a fully discrete local discontinuous Galerkin (LDG) scheme for the generalized Benjamin–Ono equation. First, we prove the L2$$ {L}^2 $$‐stability for the proposed semi‐discrete LDG scheme and obtained a suboptimal order of convergence for power nonlinear flux.

GENERALIZED AVERAGED GAUSSIAN QUADRATURE FORMULAS WITH MODIFIED MATRICES [PDF]
, 2016 Generalized averaged Gaussian quadrature formulas may yield a smaller error than Gauss quadrature rules. When moments or modified moments are difficult to compute, these formulas can serve as good substitutes.

Error bound of certain Gaussian quadrature rules for trigonometric polynomials [PDF]
, 2012 In this paper we give error bound for quadrature rules of Gaussian type for trigonometric polynomials with respect to the weight function w(x) = 1+cos x, x ∈ (−π, π), for 2π -periodic integrand, analytic in a circular domain.

Non-standard anti-Gaussian quadrature rules
Ova disertacija se bavi generalizacijom anti-Gauss-ovih kvadraturnih formula koje su uvedene 1996. godine na prostoru algebarskih polinoma. Prva generalizacija koja je urađena odnosi se na proširenje ovih formula na prostor trigonometrijskih polinoma ...

Sparse quadrature for high-dimensional integration with Gaussian measure [PDF]
, 2018 In this work we analyze the dimension-independent convergence property of an abstract sparse quadrature scheme for numerical integration of functions of high-dimensional parameters with Gaussian measure.

Efficient mass and stiffness matrix assembly via weighted Gaussian quadrature rules for B-splines [PDF]
, 2019 Calabr{\`o} et al. [10] changed the paradigm of the mass and stiffness computation from the traditional element-wise assembly to a row-wise concept, showing that the latter one offers integration that may be orders of magnitude faster.
