چکیده
Let {Ak}k=1? be a sequence of finite subsets Rd satisfying that #Ak?2 for all integers k?1. In this paper, we first give sufficient and necessary condition the existence infinite convolution?=?A1??A2????An??, where sets Ak?R+d ?A=1#A?a?A?a. Then study spectrality class convolutions generated by Hadamard triples in R construct singular spectral measures without compact support. Finally show such are abundant, dimension their supports has intermediate-value property.

Convergence of trajectories in infinite horizon optimization
In this paper, we investigate the convergence of a sequence of minimizing trajectories in infinite horizon optimization problems. The convergence is considered in the sense of ideals and their particular case called the statistical convergence. The optimality is defined as a total cost over the infinite horizon.
متن کاملWeak Convergence and Weak* Convergence1
In this article, we deal with weak convergence on sequences in real normed spaces, and weak* convergence on sequences in dual spaces of real normed spaces. In the first section, we proved some topological properties of dual spaces of real normed spaces. We used these theorems for proofs of Section 3. In Section 2, we defined weak convergence and weak* convergence, and proved some properties. By...
متن کاملImage Measures of Infinite Product Measures and Generalized Bernoulli Convolutions
We examine measure preserving mappings f acting from a probability space (Ω, F, μ) into a probability space (Ω, F , μ) , where μ = μ(f−1). Conditions on f , under which f preserves the relations ”to be singular” and ”to be absolutely continuous” between measures defined on (Ω, F ) and corresponding image measures, are investigated. We apply the results to investigate the distribution of the ran...
متن کاملWeak Convergence of Mann Iterative Algorithm for two Nonexpansive mappings
The mann fixed point algorithm play an importmant role in the approximation of fixed points of nonexpansive operators. In this paper, by considering new conditions, we prove the weak convergence of mann fixed point algorithm, for finding a common fixed point of two nonexpansive mappings in real Hilbert spaces. This results extend the privious results given by Kanzow and Shehu. Finally, we give ...
