Completely monotonic degree of a function involving trigamma and tetragamma functions [PDF]
Let $\psi(x)$ be the digamma function. In the paper, the author reviews backgrounds and motivations to compute complete monotonic degree of the function $\Psi(x)=[\psi'(x)]^2+\psi''(x)$ with respect to $x\in(0,\infty)$, confirms that completely monotonic

The derivative of a monotonic discontinuous function [PDF]
where fn(x) takes the values 0, 1/2, and 1 on the sets x xn, respectively. We modify his construction by replacing the coefficients 2-n with appropriate values cn. By hypothesis, { xn} = nE (Ej open, EjDEj+,). For each j, let E(U, k) } denote the family of components of Ej.

Monotonic Averages of Convex Functions
AbstractWe investigate the monotonicity of various averages of the values of a convex (or concave) function at n equally spaced points. For a convex function, averages without end points increase with n, while averages with end points decrease. Averages including one end point are treated as a special case of upper and lower Riemann sums, which are ...

ReMIX: Regret Minimization for Monotonic Value Function Factorization in Multiagent Reinforcement Learning [PDF]
Value function factorization methods have become a dominant approach for cooperative multiagent reinforcement learning under a centralized training and decentralized execution paradigm.

Mixture functions and their monotonicity [PDF]
We consider mixture functions, which are a type of weighted averages for which the corresponding weights are calculated by means of appropriate continuous functions of their inputs. In general, these mixture function need not be monotone increasing. For this reason we study su cient conditions to ensure standard, weak and directional monotonicity for ...

The Metastable Mpemba Effect Corresponds to a Non-monotonic Temperature Dependence of Extractable Work [PDF]
The Mpemba effect refers to systems whose thermal relaxation time is a non-monotonic function of the initial temperature. Thus, a system that is initially hot cools to a bath temperature more quickly than the same system, initially warm.

When is a monotone function cyclically monotone?
We provide sufficient conditions for a monotone function with a finite set of outcomes to be cyclically monotone. Using these conditions, we show that any monotone function defined on the domain of gross substitutes is cyclically monotone. The result also extends to the domain of generalized gross substitutes and complements.
