I just want to mention that u may think of the constraints: C\sum_{i=m+1} (q_i)^2 as if at any point in N there exist some kind of springs that tend to move the particle point to a some position in M. by definition of the properties of the coordinate system chosen, at each point in N the...

the problem formulation is the next: there is a manifold N of dimension n. inside N there is another submanifold M of dimension m\leq n. let \{q_i\} be a coordinate system over N such that q_i = 0 for i = m+1,...,n if the point given by \vec{q} is in M. let L(\vec{q}) be a lagrangian...

yes but not every vector space its a field. and that is the point here. best regards rayo

members of a vector space best regards rayo

I had just given the properties that a field must have. I just don´t know if there is a field of vectors. I had only saw division over fields. that is the way that I think of division. I think that u remains fixed the vector way of thinking. I try to remains fixed the division way of thinking...

what is a component wise product ?? :) in fact I don´t know if a vector product exists. but, if it is so, I just gave the properties that it must carry out. I´m not an expert on the field, but those properties are the one that I saw on my algebra courses. best regards rayo

think about the following ... what is dividing ?? supouse u have a set A, its elementes are a,b,c,... then supouse that u have an operation over A. say: c = a . b = b . a (for simplicity let's talk about commutative multiplication) where c in A, and a,b are any elements in A. the...

here it is all the solution to the problem... I must translate it to english. but the math it just there. http://www.4shared.com/file/43397915/94ab4035/manuscrito_1.html best regards rayo

I think it is a problem of editor in php, cause I´m on linux. so the latex compiler doesn´t work properly. anyway, I`ve had solved the remaining part of the problem. I will write it in latex, the I wil upload a .pdf file. thanks for u time. best regards rayo

look , the following text, its my first attempt to write a partial solution (it is not finished, I must resign), i have written [ tex] ... [ /tex] as a way to latex ignores those lines, but if I delete the spaces, the latex gives to me an error. I don´t know why, it seems to be right. best...

hi again tiny-tim :) ok... I forgotten to say that I´ve been solved a great part of the problem. there only remains to prove one thing. why any transformation g that preserves the galilean structure must be linear ?? if this is the case, then it need some work to figure out, but it is not...

hi tiny tim, thanks for looking my questions :) I´ve been trying to write something more specific in latex, but I had problems :P... anyway, I will try in this way. first the book (Arnold V.I. Mathematical Methods of Classical Mechanics (2ed , Springer, 1989)) talks about a galilean...

I´m editing this

hi... I´m attending a course of advanced classical mechanics. I´m working on statistical mechanics, so I´m not so familiar with some things on the course. I must solve the follwing problem for homework: [FONT="Arial"]show that every galilean transformation g on the (galilean space, using...

hi pterid ... how do u write formulas ?? best regards rayo
