How can you prove that a residue class modulo prime is a multiplicative group?

To prove that the residue classes modulo a prime ( p ) form a multiplicative group, consider the set of non-zero integers modulo ( p ), denoted as ( \mathbb{Z}_p^* = { 1, 2, \ldots, p-1 } ). This set is closed under multiplication since the product of any two non-zero residues modulo ( p ) is also a non-zero residue modulo ( p ). The identity element is ( 1 ), and every element ( a ) in ( \mathbb{Z}_p^* ) has a multiplicative inverse ( b ) such that ( a \cdot b \equiv 1 \mod p ) (which exists due to ( p ) being prime). Thus, ( \mathbb{Z}_p^* ) satisfies the group properties of closure, associativity, identity, and inverses, confirming it is a multiplicative group.

What is the difference between tensors and matrices?

A scalar, which is a tensor of rank 0, is just a number, e.g. 6 A vector, which is a tensor of rank 1, is a group of scalars, e.g. [1, 6, 3] A matrix, which is a tensor of rank 2, is a group of vectors, e.g. 1 6 3 9 4 2 0 1 3 A tensor of rank 3 would be a group of matrix and would look like a 3d matrix. A tensor is the general term for all of these, and the generalization into high dimensions.


Show that an element of a group has order n if and only if it generates a cyclic group of order n?

An element ( g ) of a group ( G ) has order ( n ) if the smallest positive integer ( k ) such that ( g^k = e ) (the identity element) is ( n ). This means the powers of ( g ) generate the set ( { e, g, g^2, \ldots, g^{n-1} } ), which contains ( n ) distinct elements. Therefore, the cyclic group generated by ( g ), denoted ( \langle g \rangle ), has exactly ( n ) elements, thus it is a cyclic group of order ( n ). Conversely, if ( \langle g \rangle ) is a cyclic group of order ( n ), then ( g ) must also have order ( n ) since ( g^n = e ) is the first occurrence of the identity.


How do you prove that the group has no subgroup of order 6?

To prove that a group ( G ) has no subgroup of order 6, we can use the Sylow theorems. First, we note that if ( |G| ) is not divisible by 6, then ( G ) cannot have a subgroup of that order. If ( |G| ) is divisible by 6, we analyze the number of Sylow subgroups: the number of Sylow 2-subgroups ( n_2 ) must divide ( |G|/2 ) and be congruent to 1 modulo 2, while the number of Sylow 3-subgroups ( n_3 ) must divide ( |G|/3 ) and be congruent to 1 modulo 3. If both conditions cannot be satisfied simultaneously, it implies that no subgroup of order 6 exists.
