ABSTRACT: This paper investigates four classes of functions with a single discontinuous point. We give the sufficient and necessary conditions under which the second order iterates are continuous ...

Applied researchers often need to estimate confidence intervals for functions of parameters, such as the effects of counterfactual policy changes. If the function is continuously differentiable and ...

For nonparametric regression, where the regression function has discontinuity points, the kernel regression estimator and cross-validation are known to be affected by ...

Point interactions for the n-th derivative operator in one dimension are investigated. Every such perturbed operator coincides with a selfadjoint extension of the n-th derivative operator restricted ...

Abstract: In computational electromagnetics and other areas of computational science and engineering, Fourier transforms of discontinuous functions are often required. We present a fast algorithm for ...

Abstract: This paper addresses the stability issue for continuous-time switched systems with stable and unstable subsystems under mode-dependent average dwell time. A homogeneous polynomial switched ...
