here i mean lie derivative of one vector field wrt another

ofcourse you would say if it is same value then we say lie derivative is zero

what i dont understand is when defining a lie derivative why is it that after a pull back or push forward the second vector field doesnt come back to its value at the pulled/pushed to point and rather have a different value

something like an app in our tablet/ipad which can recognize and associate symbols used in latex and auto generate latex code

There should be someway in which we can do the latex typing faster
