Irreducible polynomial in two variables
I'm supposed to factor (x^4)-(y^4) into a product of irreducible elements over both the fields Q[x,y] and C[x,y].
So I've factored it into (x^2+y^2)(x+y)(x-y).
Clearly the latter two ... | {"url":"http://mathhelpforum.com/advanced-algebra/128828-irreducible-polynomial-two-variables.html","timestamp":"2014-04-20T07:11:03Z","content_type":null,"content_length":"33987","record_id":"<urn:uuid:67c6b031-43f5-4909-a83a-11a7a0341759>","cc-path":"CC-MAIN-2014-15/segments/1397609538022.19/warc/CC-MAIN-201404160052... |
Guess solution to fields by minimizing the action.
Suppose I want to try and guess the fields of a short laser pulse. We know that fields that satisfy Maxwell's equations minimize the action E^2 - B^2 (say far from charge and current)?
