Quantum field theory in curved spacetime
... The special theory of relativity postulates that all inertial reference frames are equivalent. That is, the laws of physics are symmetric under the Lorentz group, which consists of all the proper Lorentz rotations. In quantum field theory, one usually makes the additional demand that physical system ...

Chapter 1 Basic Theorems from Optimal Control Theory
... with λ0 = 1 is concave in x(t) and if the transversality condition limt→∞ e−ρt λ(t)(x(t) − xo (t)) ≥ 0 holds, conditions (a) and (b) from Theorem 1 are also sufficient for an optimum. If the maximized Hamiltonian Ho (x(t), λ(t), λ0 ) is strictly concave in x(t) for all t, xo (t) is unique (but not n ...

... |+i and |−i states, corresponding to the “spin” directed parallel and antiparallel to the field ~h. You should be able to recover the field of the monopole located at the origin of the parameter space, with particular values of the monopole strength (how are those related for |+i and |−i states?) Pr ...
