Either one can be plus or minus. The colored arrows are used to make the distincions for the CCW and CW rotations.

What do CCW and CW stand for? What is the difference?

CounterClockWise and ClockWise rotations. They are not topologically equivalent, that is to say not dynamically congruent although geometrically they are.

Oh, now I remember you explained that once. One thing I don't know: 'where' is the mass? Is it between the space-time points, or 'immanent' (like inherent) sort of overlapping with them?

Using Newton's 2nd law of motion F=ma, m is the inertial mass, m=F/a. But F/a can be expressed as a matrix or Hadamard matrix. Remember, vector division is still not clearly defined in mathematics although in tensor analysis it is possible to divide a tensor by another tensor. Furthermore tensors are represented by matrices and divisions exist if and only if inverses exist.

Inverses exist if and only if the matrices are square matrices. And what does itmean that a tensor is represented by a square matrix? I think it is exactly when the tensors are sqaure matrices that they are in space-time, why? Becuase they are square matrices as they are sqaure of energy. Is this correct?

Only square matrices can mutliply itself and produce itself without creating more topologies ( there are only two and the product is just one of the two, there is no third topology) but the masses appear as scalar factors of the matrices and their numerical values increase in direct proportion to the number of repeated multiplication.
