This biannual conference, EACAT, has been held since 2007 at Seoul. Before then there had been annual China-Japan-Korea(CJK) Conference on Algebraic Topology for a few years. The conference was expanded to East Asia as Singapore, Taiwan, Vietnam topologists began to participate in 2007. Although this is a regional conference, a few European and American topologists also particiapted every year. The EACAT was held in 2008 at Singapore, 2009 at Hanoi, 2011 at Tokyo and 2013 at Beijing.

The research on nonlinear elliptic and parabolic equations is one of the most developed in Mathematics, and mightily important because of its intimate connection with other areas within Mathematics and for its wide applications in many scientific research areas such as Mathematical Physics, Mathematical Physics Chemistry, Mathematical Biology, Fluid Dynamics, Phase Transitions, and Mathematical Finance. Recently there has been a great quantity of research works regarding regularity theory for nonlinear elliptic and parabolic equations such as Calderon-Zygmund type estimates, Holder estimates, obstacle problems, homogenization, and curvature flows. This conference will concentrate on regularity theory for nonlinear elliptic and parabolic equations for the purpose of bringing together people working on this research area, discussing the current progress of development, encouraging interactions with each other, and drawing up future projects.

Feynman introduced a famuous heuristic formula which is known as "Feynman path integral" for the evolution of a nonrelavistic quantum system. The integral has been approached from many different point of view by mathematicians and physicists with varied backgound and interests. The resulting diversity has led to many different definitions of the Feynman integral. One of these approaches is to define the integral using a stochactis process, the Wiener process. Wiener process also plays an important role in stochastic calculus, applied and financial calculus and in theoretical physics such as quantum physics, statistical physics and condensed matter physics, etc. In particular, the Wiener measure can be widely applicable to the mathematical physics including quantum mechanics. The followings are shortcomings of many of the mathematical theories of the Feynman integral which are often pointed out: (1) The existence theories are not sufficiently general. In particular, many of the standard realvalued time indepent potentials which are used in modeling quantum sysytems are singlular (ex.the attractive Coulomb potenial) and do not fit within the theories. (2) No much information is given about how the various approaches to the Feynman integral are related to one another or to the unitary group which gives the evolution of the quantum systems in the standard approach to quantum dynamics. (3) There is a shortage of satisfactory limiting theorems. Indeed, in some cases, no such theorems are available, while in others, the results do not seem natural from a physical point of wiew. The goal of this workshop is that we discuss quite satisfactory responses to all three objections,especially for the approaches to the Feynman integral which are developed using Wiener integral or path integral without measures.

We plan to bring international researchers together to discuss recent developments in the theory of equations that arise as models for fluid motion. A particular focus of the conversation will be on models that feature non-local operators. The discussion is envisioned to deal with fundamental issues of local existence and regularity, but interest will devolve more to issues of singularity formation. Issues of this sort have seen sustained effort in the last decade or so, both by theoretical means and using numerical simulations. The research in this area has been carried on by groups that have largely focused upon only one type of equation. Considering the progress that has been made as well as the recalcitrance of some of the open issues, it seems timely to bring together successful workers on the various equations of fluid motion for an extended discussion of issues and methods. Especially mixing people who are numerically based with theoreticians seems propitious. More detailed commentary concerning the various perspectives we intend to embrace now follows.
