Dutt, Professor (Mathematics) at the Indian Institute of Technology Kanpur (India) due to cardiac arrest on Oct 12, 2021. Prof. Dutt obtained M.Sc. (integrated) degree in Mathematics from the Department of Mathematics and Statistics, Indian Institute of Technology Kanpur in 1980 and Ph.D. from the University of California, Los Angeles in 1985 under the supervision of Prof. Stanley Osher. He worked as Staff Scientist (ICASE), NASA Langley Research Center, Hampton USA during 1985-1987 before joining the Indian Institute of Technology Kanpur as Assistant Professor in 1987 and later became full Professor at IIT Kanpur. He made substantial contributions to Partial Differential Equations, and Numerical Analysis in a career spanning over 4 decades and published a number of articles on the theory, numerical schemes and parallel algorithms for elliptic, parabolic, hyperbolic problems, and eigenvalue problems. He had keen interest in solving PDEs with singularities on polygonal and polyhedral domains. He was a silent mathematician and deep thinker, having a calm state of mind with an amusing sense of humor. He will be deeply missed by all his students, friends and colleagues. ------------------------------------------------------- From: Laurence Halpern [log in to unmask] Date: October 22, 2021 Subject: Launch of the Olof B.

The RTD-A position is considered the first significant step of the academic career in Italy. Despite being strictly a fixed-term contract with the duration of three years, it is a staff position giving right of vote in the Council of the Department, full access to labor and pension rights (with a gross salary around 35000 Euro/year), and requiring some teaching duties (about one course per annum). It can also be prolonged for two (but no more than two) years subject to availability of funding and mutual interest. The position has to be viewed in the context of the multi-decades research collaboration between the Department of Computer Science of the University of Pisa and M.A.I.O.R. S.r.l. https://www.maior.it/en . The research activity will address decision-making processes in organized systems, with particular focus to, but not exclusively, those relating to Local Public Transport. The research considers all the different phases that characterize the decision-making process: the definition of the problem, its mathematical formalization, the formulation of constraints, objectives and action alternatives, the development of solution algorithms as well as their implementation, evaluation and certification. Besides the methodological and theoretical aspects, the research will focus on the development of efficient and well-engineered software implementing the proposed approaches for the solution of either large-scale structured optimization problems or of sub-problems with specific structures that can result from the application of algorithmic methodologies (decomposition, implicit enumeration, large-scale local search, ...) to the original problems. A proper balance will be struck between the development of algorithms for general classes of problems and for the specific problems encountered by M.A.I.O.R. within planning and management (operational and real time) of Local Public Transport systems. The call can be found at https://alboufficiale.unipi.it/wp-content/uploads/2021/10/Bando_RTDA_PON_43.pdf (it's one of 43 positions, check the record RIC2021PON_A19) and the strict deadline for applications is 13:00 November 4, 2021 (Italian time).

The position is associated with a third-party funded research project led by Dr. Jia-Jie Zhu (WIAS Berlin) and Dr. Michael Hintermuuller (WIAS/ Humboldt- Universitat zu Berlin). The initial funding period will run for two years, starting January 1st, 2022. The applicants should have completed their Ph.D. degrees by the starting date of the project. Motivated by numerous partial differential equation (PDE) related practical applications, a pressing challenge for data-driven optimization and control systems is the ubiquitous distribution shift, which implies higher demand for the robustness of the learning-for-control design. The project, funded by the Excellence Cluster MATH+: The Berlin Mathematics Research Center, aims to address data-driven robust control and optimization of dynamical systems under data distribution shifts, using principled tools from applied mathematics and statistical machine learning as well as reinforcement learning. We invite candidates whose scholar profiles are mainly theoretical and exhibit proven excellence in research. We specifically prefer two types of mathematical research experiences: (1) either in principled statistical machine learning/reinforcement learning theory (related to dynamical systems, time series, Markov decision process (MDP), principled control theory). Those qualifications are demonstrated, among others, by high-quality publications in credible venues such asNeurIPS/ICLR/AISTATS/ICML/CoLT/JMLR/L4DC. (2) and/or in applied mathematics, in optimization, numerical analysis, optimal control, dynamical systems (PDEs and S(P)DEs), data-driven modeling of dynamics, theory of model predictive control (MPC). Those qualifications are demonstrated, among others by relevant publications in credible venues such as SIAM OPT/CON/COAP/COCV/MathProg.
