In mathematics, Hörmander's condition is a property of vector fields that, if satisfied, has many useful consequences in the theory of partial and stochastic differential equations. The condition is named after the Swedish mathematician Lars Hörmander For partial di erential equations the corresponding representation is u(x) = Z P(˘)=0 ei(x;˘) (d˘); (2) where is an arbitrary distribution from a certain class. In particular, is the measure if the roots of P(˘) are simple (L. Ehrenpreis, 1954). Representation (2) follows from the fact that equation (1) considered in Rn is equivalent to the equality 0.1.
