The Single Conservation Lawation of the approximants, rather than (the usually encountered) bounds on derivatives, since the latter bounds would imply via the standard compactness criteria, that the limit would be .; we know that this is not generally true.

The One-Dimensional Wave Equationwill be used in various places throughout the book, albeit at a “higher dialectical” level. The equation is derived from physical considerations, and in the case we consider here, the solution .(., .), may be thought of as describing the position of a vibrating string at a point . at a time ..

Second-Order Linear Parabolic Equationsthe fact that the equations are not invariant under the reversal of time; i.e., under the transformation . → −.. This means that knowledge about the “past” is lost as time increases. For example, there may be dissipation effects which lead to an increase in entropy and a consequent loss of information.
