Preface
The 11th International Conference on Large-Scale Scientific Computations (LSSC
2017) was held in Sozopol, Bulgaria, June 5–9, 2017. The conference was organized
by the Institute of Information and Communication Technologies at the Bulgarian
Academy of Sciences in cooperation with Society for Industrial and Applied Mathe-
matics (SIAM) and Sozopol municipality.
The plenary invited speakers and lectures were:
– J. Adler, “Energy-Minimization, Finite Elements, and Multilevel Methods for
Liquid Crystals”
– J. Gopalakrishnan, “Theoretical and Practical Aspects of DPG Methods”
– U. Langer, “Multi-Patch Discontinuous Galerkin Space and Space-Time Isogeo-
metric Analysis”
– J. Pasciak, “Numerical Approximation of a Space-Time Fractional Parabolic
Equation”
– G. G. Yin, “Numerical Methods for Consensus of Networked Systems and
Stochastic Control with Soft Constraints”
The success of the conference and the present volume are the outcome of the joint
efforts of many partners from various institutions and organizations. First, we would
liketothankallthemembersoftheScientificCommitteefortheirvaluablecontribution
forming the scientific face of the conference, as well as for their help in reviewing
contributed papers. We especially thank the organizers of the special sessions. We are
also grateful to the staff involved in the local organization.
Traditionally, the purpose of the conference is to bring together scientists working
with large-scale computational models in natural sciences and environmental and
industrialapplications,andspecialistsinthefieldofnumericalmethodsandalgorithms
for modern high-performance computers. The invited lectures reviewed some of the
most advanced achievements in the field of numerical methods and their efficient
applications. The conference talks were presented by researchers from academic
institutions and practical industry engineers including applied mathematicians,
numerical analysts, and computer experts. The general theme for LSSC 2017 was
“Large-Scale Scientific Computing” with a particular focus on the organized special
sessions.
The special sessions and organizers were:
– Space-Time Methods for Solving Time-Dependent PDEs — U. Langer
– Advanced Discretizations and Solvers for Coupled Systems of Partial Differential
Equations — J. Adler, X. Hu, L. Zikatanov
– Least-Squares Finite Element Methods — F. Bertrand and P. Bochev
– Advances in Heterogeneous Numerical Methods for Multi Physics Problems
