A field is a function that describes a physical quantity at all points in space. A physical quantity can be either a scalar or a vector; thus, a field can also be a scalar field or a vector field. A ...

Ticciati's approach to quantum field theory falls between building a mathematical model of the subject and presenting ... The book is divided into five parts: canonical quantization of scalar fields, ...

such as Brans-Dicke's theory, also promotes Newton's constant G to a scalar field. This led to the dynamics, which mimics the ...
