Paradoxes and Expansions

The tremendously complex world of today's mathematics makes us wonder about its genesis and rules of its creation. Here we show several ways of growing of mathematical subjects.

Mathematicians love to think about problems without solutions. To solve the paradox, one usually extends the notion of solution. Since the solutions of math problems are numbers or functions, the expansion leads to generalizing of definition of them.

For example, consider an ``incorrect'' system of two equations that does not have a solution:

\begin{displaymath}
\left\{ \matrix{ x=0\cr x=2.} \right.
\end{displaymath}

Depending on the origin of the problem, one may consider an expansion of the very definition of what ``solution'' is: Besides, one should examine the adequateness of the modeling or logic of derivation of the contradictory system.
