Hi,

How does one raise or lower indices of tensors when one is using the atlas package. Do we have to create a table and then use the inbuilt maple command raise/lower to do this or can one do this within the atlas package.

thanks

Hi,

When maples calculates Riemenn or Ricci tensor it displays the result in a notation which takes many lines or even pages. Can one replace derivatives with respect to x, y and z as fx, fy, fz instead of what is given by diff(f(x,y,z),x) etc.  and denote partial derivative with respect to t as just a dot. ( I know that maple can use dot to denote total derivative but I want it to denote partial derivative). and Can one write f(t,x,y,z) simply as f. These are...
