Are you wanting to add a string property in Wikidata to store MathML equations and formulas?

As I side note, when I look here I get a bunch of script errors starting halfway down the page.

> Hi,

> I have one question concerning wikidata:
> at
> http://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation#Time-dependent_equation
> we have the statement
> Ψ is the wave function
> I have developed a system that discovers the relation between Ψ and
> the page wave function
> Is there a way to model that in wikidata or should I use another way
> to model that relationship?
> If so could someone show me how to model the relationship from the
> example above.
