In the question https://mathematica.stackexchange.com/search?q=non+newtonian, I use "dstar" as acronym to multiplicative derivative. But in the standard literature the symbol i $f^\star$. How can I, if it is possible define this type of symbol and use it --- or $D^\star$


Use the Notation package. You first need to run


which brings up a palette that you can use to enter notation. Since this is hard to write down, I am posting a gif showing how it is done. Use Esc+star+Esc to get the $\star$ symbol.
