A tensor could be also a vector.One call it a one tensor.A rotation is only a mathematical construction.Of course, a boost is also a rotation but with a physical meaning involved .Here you make a rotation in a Lorentz invariant manner.So the (relativistic)physics holds under this specific...
Maybe you can also try Hubbard ,Vector Calculus,lineare Algebra and differential forms.It is didactically one of the best books on this level.
Here is nice picture to the Lemma:
Not in all cases.In the language of mathematical physics one argue in strict mathematical language.Some theoretical physics profs prefer this language to describe physics.For example the canonical quantization for Boson particles without gauge potentials uses this formalism.I have actually one...
Do we talk about closed curves?Because
A curve is the image of a continuous function from an interval to a topological space(Wikipedia ).Doesn't this mean a curve implies per definition open neighbourhoods?
Hello guys,
I struggle with one step in a calculation to show a quantum operator equality .It would be nice to get some help from you.The problematic step is red marked.I make a photo of my whiteboard activities.The main problem is the step where two infinite sums pops although I work...
I would say no because of this pairwise description which you have stated above.Maybe some combinatorial arguments are missing to expand the concept to include also such cases.
If your energy is conserved which means there exist no perturbation from outside the energy environment then you have T+V=E=constant or equivalent dE\dt=0 .So,you have an fixed Energy value which will transform from the kinetic/-to potential energy and vice versa.Therefore both types of...
Sorry,but I don't understand your question not good enough to give you an answer.Try to make your question a little bit more concrete.Maybe you should post the reference where question is related to.
Wasn't this link to my reddit profile not enough which I had posted yesterday ?Maybe you You can give me some straight instructions what you are concretely mean by this.
Thank you and best regards
