**Geometric Methods for Quantum Field Theory**Both mathematics and mathematical physics have many active areas of research where the interplay between geometry and quantum field theory has proved extremely fruitful. Duality, gauge field theory, geometric quantization, Seiberg-Witten theory, spectral properties and families of Dirac operators, and the geometry of loop groups offer some striking... | | **Active Defense: A Comprehensive Guide to Network Security**Today's networks incorporate more security features than ever before, yet hacking grows more common and more severe. Technology alone is not the answer. You need the knowledge to select and deploy the technology effectively, and the guidance of experts to develop a comprehensive plan that keeps your organization two steps ahead... | | **Managerial Leadership**
