**Martin Lazar** is a Research professor at University of Dubrovnik, Croatia. His fields of research are Control of parameter dependent systems (greedy control, averaged control), optimal control of parabolic problems. Microlocal analysis; PDEs and homogenisation, velocity averaging, microlocal defect functionals (1-scale H-measures, semiclassical measures, H-distributions), and Geophysical fluid dynamics; analytical modelling in oceanography.

#### Author's contribution:

#### Turnpike property for functionals involving $L^1$−norm

We want to study the following optimal control problem...

#### Greedy optimal control for elliptic problems and its application to turnpike problems

Turnpike theory and greedy algorithms, applied to the steady-state elliptic control problem, are combined to obtain a greedy approximation of parabolic optimal control problems, independent of the initial data

#### Greedy Control

Control of a parameter dependent system in a robust manner
