Priyadarshi Dey and Monika each gave a presentation at the Special Session of the International Workshop in Operator Theory and Applications in July 2019 at Instituto Superior Técnico in Lisbon, Portugal. The presentations were entitled "Bicircular Projections on Some Operator Spaces" by Dey, and "Quotient Operators on Tensor Product Spaces" by Monika.
Marcelo Bongarti and Stephen Guffey spent 10 weeks during Summer 2019 working on National Science Foundation sponsored research programs at the Argonne National Laboratory in Chicago.
- Guffey's research project, under the mentorship of Dr. Sven Leyffer and Johann Rudi, entitled "Numerical Determination of Optimal Controls for a Bolza Problem for a Chemotactic System" consisted of investigating and finding optimal controls numerically using finite difference schemes. The schemes were implemented in the programming language AMPL, and numeric solution for the PDE system was attempted using Python. Chemotactic systems are systems of strongly coupled nonlinear partial differential equations of parabolic type. Wellposedness and controllability of PDE's describing chemotactic system is the subject of Steven's PhD dissertation.
- Bongarti's research project, under the mentorship of Dr. Paul Hovland and Dr. Sri Hari Krishna Narayan was entitled "Efficient Quantum Optimal Control Algorithms". The goal of the project was to investigate how one could take advantage of the fact that the quantum evolution operators are unitary in order to optimize the memory usage within quantum optimal control algorithms. The research involved deals with Schrodinger operators and a control of the underlined dynamics. The results obtained will be considered for journal publication.
