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 ...

This paper studies the convergence rate of randomized quasi-Monte Carlo (RQMC) for discontinuous functions, which are often of infinite variation in the sense of ...

Abstract: In this letter, without assuming the boundedness of the activation functions, we discuss the dynamics of a class of delayed neural networks with discontinuous activation functions. A relaxed ...

Abstract: We consider a capital equipment replacement problem where the assets available for purchase evolve over time according to continuous and discontinuous functions of technological change.
