Discretization methods for nonconvex differential inclusions
Electronic Journal of Qualitative Theory of Differential Equations, 2009 We prove the existence of solutions for the differential inclusion $\dot x(t)\in F(t,x(t)) + f(t,x(t))$ for a multifunction $F$ upper semicontinuous with compact values contained in the generalized Clarke gradient of a regular locally Lipschitz function ...

From gateway to value ladder—The curious case of online mutual aid in China
Journal of Risk and Insurance, EarlyView.Abstract This study examines how InsurTech‐enabled information provision, specifically the disclosure of claimant information previously unavailable in conventional insurance, influences individuals' insurance uptake. We leverage Mutual Aid (MA) platforms as a natural context to examine how socially framed loss information, peer influence, and salience

Beyond Convexity: Stochastic Quasi-Convex Optimization
, 2015 Stochastic convex optimization is a basic and well studied primitive in machine learning. It is well known that convex and Lipschitz functions can be minimized efficiently using Stochastic Gradient Descent (SGD).

Distributed convergence to Nash equilibria in two-network zero-sum games [PDF]
, 2012 This paper considers a class of strategic scenarios in which two networks of agents have opposing objectives with regards to the optimization of a common objective function.

A Multiplicity Theorem for Locally Lipschitz Periodic Functionals
Journal of Mathematical Analysis and Applications, 1995 The authors consider the periodic multivalued problem of the forced pendulum \[ \begin{cases} x''(t) + f(t)\in \biggl[\underline g\bigl(x(t) \bigr), \overline g \bigl(x(t) \bigr)\biggr], \quad \text{a.e. } t\in(0,1) \\ x(0) = x(1),\;x'(0) = x'(1) \end{cases} \] where \(f\in L^p(0,1)\), \(g\in L^\infty (\mathbb{R})\) is periodic of period \(T\), the ...

Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...

Existence of fixed points on compact epilipschitz sets without invariance conditions
Fixed Point Theory and Applications, 2005 We provide a new result of existence of equilibria of a single-valued Lipschitz function f on a compact set K of â„Ân which is locally the epigraph of a Lipschitz functions (such a set is called epilipschitz set).

Local convergence of exact and inexact newton’s methods for subanalytic variational inclusions
Revista de Matemática: Teoría y Aplicaciones, 2015 This paper deals with the study of an iterative method for solving a variational inclusion of the form 0 ∈ f (x)+F (x) where f is a locally Lipschitz subanalytic function and F is a set-valued map from Rn to the closed subsets of Rn.
