stability analysis, routh-hurwitz criterion, jacobi matrix [urgent] Hello, I have got a quite urgent questions regarding stability analysis of a three dimensional of differential equations. I don't quite understand how this works in that case or more which method the author uses. I have got the Jacobi matrix of the dynamic system which is linearized around a fixed point (st... 26 Jul 2010 14:57
Energy of whole atom radiates at fusion/fission But the radiation energy must come out of a single particle not the whole atom. So how does the difference in atom mass end up in one particle of the atom to be radiated? And what particle out of the many would get chosen for the energy difference and how?

Is this problem NP-hard? Hello, I've run across the following combinatorial optimization problem, and while it's a very straightforward problem I haven't been able to find it discussed in the literature. Can anyone suggest any thoughts or references on the matter? The input to my problem is a collection of "jobs", each with a start ti... 26 Jul 2010 17:10
Question about maximality principles, lattices, AC and its equivalents I'm really sorry. (DMI) isn't the same as (DPI), I forgot to write the (DMI) statement. In fact, according to the book I'm reading, (DPI) cannot imply (AC). Here is the (DMI) statement: (DMI): Every distributive lattice with 1, which has more than one element, contains a maximal ideal. Once again, I'm sorry... 25 Jul 2010 23:48
misleading idea of contradiction proofs; Twin Primes must have a Euclid type proof #4.17 Correcting Math Now I was asking Lwalk in a prior post, and hope he does not ignore the question. The question was that since Euclid Infinitude of Primes proof, both direct and indirect yield the infinitude of Regular primes and since the twin primes are a subset. One has to wonder, logically, that logic demands the same apparatu... 25 Jul 2010 04:25
