On R-valued peacocks
نویسندگان
چکیده
In this paper, we consider R-valued integrable processes which are increasing in the convex order, i.e. R-valued peacocks in our terminology. After the presentation of some examples, we show that an R-valued process is a peacock if and only if it has the same one-dimensional marginals as an R-valued martingale. This extends former results, obtained notably by V. Strassen (1965), J.L. Doob (1968) and H. Kellerer (1972).

Universal Approximation of Interval-valued Fuzzy Systems Based on Interval-valued Implications
It is firstly proved that the multi-input-single-output (MISO) fuzzy systems based on interval-valued $R$- and $S$-implications can approximate any continuous function defined on a compact set to arbitrary accuracy. A formula to compute the lower upper bounds on the number of interval-valued fuzzy sets needed to achieve a pre-specified approximation accuracy for an arbitrary multivariate con...
متن کاملMartingales Associated to Peacocks Using the Curtain Coupling
We consider right-continuous peacocks, that is families of real probability measures (μt)t that increase in the convex order. Given a sequence of time partitions we associate the sequence of martingales that are Markovian, constant on the partition intervals [tk, tk+1[, and designed in a way that the transition kernels at times tk+1 are the curtain couplings of marginals μtk and μtk+1 . We stud...
متن کاملPointfree topology version of image of real-valued continuous functions
Let $ { mathcal{R}} L$ be the ring of real-valued continuous functions on a frame $L$ as the pointfree version of $C(X)$, the ring of all real-valued continuous functions on a topological space $X$. Since $C_c(X)$ is the largest subring of $C(X)$ whose elements have countable image, this motivates us to present the pointfree version of $C_c(X).$The main aim of this paper is to present t...
متن کاملThe ring of real-valued functions on a frame
In this paper, we define and study the notion of the real-valued functions on a frame $L$. We show that $F(L) $, consisting of all frame homomorphisms from the power set of $mathbb{R}$ to a frame $ L$, is an $f$-ring, as a generalization of all functions from a set $X$ into $mathbb R$. Also, we show that $F(L) $ is isomorphic to a sub-$f$-ring of $mathcal{R}(L)$, the ring of real-valued continu...
متن کاملBiomechanics of the Peacock’s Display: How Feather Structure and Resonance Influence Multimodal Signaling
Courtship displays may serve as signals of the quality of motor performance, but little is known about the underlying biomechanics that determines both their signal content and costs. Peacocks (Pavo cristatus) perform a complex, multimodal "train-rattling" display in which they court females by vibrating the iridescent feathers in their elaborate train ornament. Here we study how feather biomec...
