can the 4 momentum (since it is a vector) be considered an operator?

Yes, momentum is considered to be an operator in quantum mechanics. It is represented by the symbol p and is defined as the rate of change of an object's position with respect to time.
Momentum, as an operator, plays a crucial role in quantum mechanics as it is used to describe the motion of particles and is a fundamental quantity in determining the energy and position of a particle.
In quantum mechanics, momentum is represented by the momentum operator, which is defined as p̂=-iħ∇, where ħ is the reduced Planck's constant and ∇ is the gradient operator.
No, the momentum operator can only be applied to quantities that are physically measurable and have a well-defined position and momentum in quantum mechanics.
The commutator relationship between the position and momentum operators is given by [x, p̂]=-iħ, where x is the position operator and p̂ is the momentum operator. This relationship is a fundamental aspect of quantum mechanics and is used to determine the uncertainty in the measurement of position and momentum of a particle.
