Modern Mathematical Physics: what it should be?
Ludwig Faddeev
Personal view of author on goals and content of Mathematical Physics.
From Yang-Mills Field to Solitons and back again
L. D. Faddeev
Lecture delivered at XXXVI Summer School on Subnuclear Physics at Erice in September 1998. It contains a brief reflection on the development of QFT in late sixties and a discussion…
Algebraic Quantization of Integrable Models in Discrete Space-time
L. D. Faddeev, A. Yu. Volkov
Just like decent classical difference-difference systems define symplectic maps on suitable phase spaces, their counterparts with properly ordered noncommutative entries come as He…
Shift Operator for Nonabelian Lattice Current Algebra
L. Faddeev, A. Yu. Volkov
The shift operator for a quantum lattice current algebra associated with sl(2) is produced in the form of product of local factors. This gives a natural deformation of the Sugawara…
How Algebraic Bethe Ansatz works for integrable model
L. D. Faddeev
I study the technique of Algebraic Bethe Ansatz for solving integrable models and show how it works in detail on the simplest example of spin 1/2 XXX magnetic chain. Several other…
