This category contains all control problems which are governed by a parabolic partial differential equation.
A second order linear partial differential equation can be written as
.
If 
is positive or negative semidefinite with exact one eigenvalue zero, the partial differential equation is called parabolic.
An example is the heat equation: 
,
where 
denotes the Laplace operator, 
is the unknown, and the function 
is given.
