Reflections about disscusions of love intensity ...

Hi everybody!
The problem of single value or multivalue function is really not
important...
In fact if we have a multivalue function f from X into Y, then we can
regard f as a single value function from X to 2^{Y} (a set of all subsets
of Y). 

For long time mathematicians and math. physicists have studied intensively
systems with relational evolutional equations.  These systems have many
interesting properties ....
