Query: Line integration and second order partial differential equations over
  Cayley-Dickson algebras   Line integration of generalized functions is studied. Second order partial
differential equations with piecewise continuous and generalized variable
coefficients over Cayley-Dickson algebras are investigated. Formulas for
integrations of such equations are deduced. For this purpose a non-commutative
line integration is used. Examples of solutions of partial differential
equations are given.
