Introduction to the h-Principle 2/e Helen Rogers and yet few of usIn differential geometry and topology one often deals with systems of partial differential equations as well as partial differential inequalities that have infinitely many solutions whatever boundary conditions are imposed. It was discovered in the 1950s that the solvability of differential relations (i. e., equations and inequalities) of this kind can often be reduced to a problem of a purely homotopy theoretic nature. One says in this case that the
