Visualization of minimal time needed to get by public transport and walking from any point in Vienna to its city center.
About me
I am PhD graduate in mathematics at the University ParisSaclay in France and University of Vienna in Austria. My advisors were Alin Bostan and Herwig Hauser and my interests are integer sequences, differential operators and algebraic power series. I also have a master's degree in mathematics and another one in quantitative finance.
