RMITOpt Talk: Extending de Bruijn’s Identity – Prof. Bill Moran


Speaker: Prof. Bill Moran

Title:  Extending de Bruijn’s Identity

Date and Time:  Friday, April 27th, 3.00pm – 4.00pm

Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus (To connect via visimeet  please contact

Abstract:    The de Bruijn’s identity is a classical result in Information. Theory relating two well-known measures of information in distributions: Shannon Entropy and Fisher Information. It measures, in terms of the Fisher Information, how the entropy of a distribution increases as it evolves under Brownian noise. The original identity was proved for distributions on the real line, but is not hard to extend to n dimensions.

Our work has attempted to find analogues in the context of Riemannian manifolds. There, it is not even clear, ab initio, what the statement of the theorem should be. Our approach requires extension of the notion of Intrinsic Fisher Information to Riemannian manifolds. From this we are able to show that a probabilistic solution to the heat equation results in a heat equation for the entropy density of this solution, but with a source term that arises from the Fisher Information density. Combined with the Li-Yau inequality this lead to bounds on the rate of increase of entropy on a manifold. The seminar will discuss ideas around Fisher Information, forms on manifolds, and the heat equation, as well as a little history of the identity.  This is joint work with Stephen Howard (DST Edinburgh), Doug Cochran (Arizona State U).

Title:  Common fixed points of monotone Lipschitzian semigroups in Banach spaces

Date and Time:  Friday, April 13th, 3.00pm – 4.00pm

Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus (To connect via visimeet  please contact

Abstract:     We will discuss the existence of common fixed points of monotone Lipschitzian semigroups in Banach spaces under the natural condition that the images under the action of the semigroup at certain point are comparable to the point. In particular, we prove that if one map in the semigroup is a monotone contraction mapping, then such common fixed point exists. In the case of a monotone nonexpansive semigroup we prove the existence of common fixed points if the Banach space is uniformly convex in every direction. We explain why these assumptions are substantially weaker than those made in the pre-existing literature. We will also touch upon some non-trivial applications, as well as on recent research directions in the field.

RMITOpt Seminar this Friday the 23rd March at 1.30pm – Dr. Anand Deopurkar, ANU


  Speaker: Dr. Anand Deopurkar

Title:  The algebra and geometry of algebraic varieties

Date and Time:  Friday, March 16th, 1:30pm – 2.30pm

Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus (To connect via visimeet  please contact

Abstract:     Abstract: An algebraic variety is the set of common zeros of a collection of polynomial equations. A central theme in algebraic geometry is to understand the connection between the geometric properties of the zero set (for example, curvature) and the algebraic properties of the polynomials (for example, degrees). I will explain known and conjectural results in this area with lots of examples.

Bio:   Anand is lecturer at the Australian National University. Before coming to ANU, he was a post-doc at Columbia University and the University of Georgia, and before that, a graduate student at Harvard.

Anand studies moduli spaces of algebraic varieties. That is, he tries to understand how algebraic varieties deform when the defining equations are perturbed. In addition to algebraic geometry, he enjoys thinking about problems in algebra, number theory, and representation theory.

Talk by Bertrand Jouve, March the 16th


  Speaker: Bertrand Jouve

Title:  Using graph theory for the study of medieval social network

Date and Time:  Friday, March 16th, 3:00pm – 4.00pm

Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus (To connect via visimeet  please contact

Abstract:    We show how classical and new tools of graph theory may be used for studying medieval sources. The large-scale processing of information contained in agrarian contracts between 1250 and 1550 allows to propose forms of social organizations of the peasant world of the south of France that bring new points of view to some major questions posed by historians.

Bio:   Bertrand Jouve is a senior researcher at the French National Centre for Scientific Research (CNRS). He studied pure mathematics, passed the agrégation in Mathematics and, in 1999, was awarded a doctorate (PhD) in Cognitive Sciences under the supervision of Pierre Rosenstiehl (mathematician) and Michel Imbert (neuroscientist) at the Higher School of Social Sciences (EHESS, Paris). First an Assistant Professor in Toulouse, then a Full-Professor of Applied Mathematics in Lyon, he was appointed Senior Researcher by the CNRS 53 interdisciplinary Commission in 2014. Bertrand Jouve’s work focuses on the construction of mathematical models of graph theory to be used for the analysis of large-scale interaction networks. Over a decade, he has worked at the boundary of neurosciences on the topological structure of cortico-cortical neural connections of monkey brains. Since 2004, he has been working at the boundary of Social Sciences and Humanities. He first collaborated with linguists on the structure of language dictionaries, with sociologists to analyze large-scale social networks and with historians with a view to reconstructing former complex social networks. Bertrand Jouve created the Toulouse Institute for Complex System Studies (XSYS) in 2014. Bertrand Jouve is engaged in the national administration and strategy of French research. He was a member of the CNRS board between 2011 and 2016 and member of the CNRS Committee for Intensive Computing. Since June 2016, he has been President of the National Network of 23 Houses of Social Science and Humanities (RNMSH) which is a part of the French national strategy for excellence in Social Sciences and Humanities.


Talk by Asen Dontchev in early March





Speaker: Asen Dontchev

Title: Constrained Spline Interpolation

Date and Time:  Friday, March 2nd, 3:00pm – 4.00pm

Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus (To connect via visimeet  please contact

Abstract: It is well known that the interpolating cubic spline can be viewed as a solution of an optimal control problem. This fascinating connection between the classical approximation theory and the theory of optimal control has been explored by researches from both sides in different times and often independently. In this talk I will review some developments on spline interpolation with constraints.  In particular, I will show how a long-standing open question about super-linear convergence of Newton’s method for best convex interpolation has been settled.

Final Presentation Healthier/RMIT by Iman Roozbeh at RMIT January the 16th


  Speaker: Iman Roozbeh

Title: Improving the optimisation of automated meal plan generation through a combination of specific health information and personal preferences

Date and Time:  Tuesday, January 16, 10:30am – 11:30am

Location:  Building 8 Level 9 Room 66 (AGR) RMIT City campus

Abstract:  Proper dietary guidance is a critical component of chronic disease management. However, just 5,000 dietitians operate in Australia to serve the estimated 7 million people currently living with chronic disease. Our current approach to delivering health care is not coping now and it certainly won’t in the future. Dietitians face the challenges of integrating complex scientific information, lifestyle and food preferences, applied to a range of medical conditions. Dietitians cannot provide personalised meal plans to every client because the process is too time consuming and many do not have adequate training.

To address these issues, Health Delivered is developing a dietary management platform to tackle the growing rates of obesity, diabetes and other chronic health issues by building customised meal plans for patients. The platform has been created to build meal plans that account for social, personal and medical history as well as health goals and personal preferences, in an efficient manner and assist dieticians to see more number of clients and focus on quality of client care.
