Introduces methods of complex variables, contour integration, and theory of residues. Applications include solving partial differential equations by transform methods, Fourier and Laplace transforms, ...

We review aspects of twistor theory, its aims and achievements spanning the last five decades. In the twistor approach, space–time is secondary with events being derived objects that correspond to ...

Complex Langevin dynamics has emerged as a powerful technique to tackle the sign problem inherent in quantum field theory simulations. By extending the configuration space into complex domains, this ...
