A large part of science and engineering work requires equations which model and analyze various situations. In many cases, these equations soon become complex and hard to resolve or solve analytically ...

The theories of high speed aerodynamics described in this volume, on the basis of which a quantitative study of the characteristically “nonlinear” effects is made in the present section, are those ...

We construct a family of approximations of the Riemann zeta-function and a closely related function formed from finite Euler products, the pole of the zeta-function, and any zeros the zeta-function ...
