    Are complete groups abelian?

    Hi: Let $G$ be a group and $G'$ it's commutator subgroup. Then $G > G' > 1$ is a series of normal subgroups of $G$. Suppose $G$ is complete. Then, if I'm not wrong, $Aut(G)$ is the stabilizer of that series. But then, by a theorem, $Aut(G)$ is nilpotent of class <= 1, that is $Aut(G)' = 1$ and...

    prove q are not complete

    From the definition : Q is complete iff every non empty bounded from above,subset of Q HAS A sUPREMUM IN Q,WE CAN INFER that Q is not complete: if there exists a non empty,bounded from above subset of Q that it has no Supremum belonging to Q. So the main idea is to find a non empty ,bounded...

    Eigenvalues of complete partite Graphs.

    The eigenvalues of complete bipartite graph(Km,n) is given by the expression ±√m*n , 0(with multiplicity k-2). Where k is number of nodes in the graph. I am looking for generalization of the expression for eigenvalues of complete n-partite graphs. Does such a expression exists for complete...

    Find Indefinite Integral: Complete the Square

    Must I complete the square of the denominator? If so, after completing the square my answer is (x+1)^2 + (1/2). I then set a to be sqrt(1/2) and u to be x+1, which means dx = du. Is this right so far. Can someone rotate this picture for easy reading?

    Using matrix to complete the square

    Given a quadratic form: x^2 - 4xy + 6xz + 2xt + 4y^2 + 2yz + 4yt + 5z^2 - 6zt - t^2, find the symmetric matrix that defines this, row reduce this matrix into row echelon form, and use this upper triangle matrix to complete the square and write the quadratic form as the sum/difference of squares...

    Graph or complement contains complete graph

    I am trying to prove that given any graph G on 4^n vertices, either G or its complement contains K_n (the complete graph on n vertices) as a subgraph. I am tutoring students who have not had any graph theory, and they are supposed to approach the problem combinatorially (supposedly just applying...

    How do you complete the square with a negative coefficient?

    Hi guys basically I have got a bit of a problem with completing the square... If I had to complete the square of x2-14x+36=0 I would form the square of (x-7)2 I would then expand the brackets to get x2-14x+49 I would then combine this with the original equation to get x2-14x+49+36=0...

    Do we have a complete knowledge of calculus or is it a study in development?

    I was wondering since I never hear of anyone studying mathematics to do advance "calculus". More generally, can calculus be categorized as a pure math?

    Number of subgraphs within a complete graph

    How many subgraphs with at least one vertex does K3 (a complete graph with 3 vertices) have? I know that K3 is a triangle with vertices a, b, and c. From asking for help elsewhere I was told the formula for the number of subgraphs in a complete graph with n vertices is 2^(n(n-1)/2) In this...
