Vadim Knizhnik was once essentially the most promising theoretical physicists on the earth. regrettably, he passed on to the great beyond on the very younger age of 25 years. This memorial quantity is to honor his contributions in Theoretical Physics. this can be probably some of the most vital collections of articles at the theoretical advancements in String idea, Conformal box conception and comparable subject matters.

We now quantize the ﬁeld by imposing the canonical quantization rule, mentioned in Chapter 8, namely: [φ(x, t), φ(x , t)] = [π(x, t), π(x , t)] = 0 [φ(x, t), π(x , t)] = iδ 3 (x − x ) where π(x, t) ≡ ∂L/∂(∂φ/∂t) = ∂φ/∂t. These commutation rules become commutation relations among a(k)’s and a∗ (k)’s, thus: [a(k), a(k )] = [a∗ (k), a∗ (k )] = 0 [a(k), a∗ (k )] = δ 3 (k − k ).

The question then is what is the clue and prescription by which we can introduce interactions into the Lagrangian densities. There are very few clues. In fact, there is only one known prescription to introduce electromagnetic interactions and it comes from the Hamiltonian formalism of classical physics, as discussed in Chapter 2.

The Klein– Gordon equation is a second-order diﬀerential equation — second derivatives with respect to both space and time — and as a relativistic equation for single particle, it encounters some diﬃculties; the nature of second-order diﬀerential equations and the probability interpretation of quantum mechanics clash. ) Rather than a second-order equation, Dirac wanted a ﬁrst-order linear equation containing only the ﬁrst derivatives with respect to both space and time, that is, linear with respect to four-vector derivates.
