Dual subgradient method with averaging for optimal resource allocation
Message from the ICPP 2015 Workshop Co-Chairs We would like to welcome everyone to the International Conference on Parallel Processing (ICPP) 2015, in Beijing, China. Workshops are an integral part of the ICPP conference series and have been an area of focus for attendees at ICPP for the past many years. This year, we have a great selection of six workshops focusing on various topics including parallel programming models and systems software, power-aware computing, wireless and sensor networks, embedded multicore systems, resource management, and big data computing. The workshops will be held on September 1, 2015. We would like to thank the organizers of these six workshops for helping to put together a fantastic workshops program that complements the main conference program in newer and more focused topic areas. We would also like to thank the general co-chairs, Prof. Yuanyuan Yang and Prof. Jianping Wu; the program co-chairs, Prof. Pavan Balaji and Prof. Mingwei Xu; and the publications chair, Prof. Wang-Chien Lee, for their help and support throughout the conference. We hope that you participate in and enjoy the workshops program. We look forward to seeing you in Beijing, China. Best regards, Anne Benoit, ENS Lyon, France Wenguang Chen, Tsinghua University, China ICPP 2015 Workshop Co-Chairs
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
