Kernel of a group homomorphism
In this video I introduce the definition of a kernel of a group homomorphism. It is simply the set of all elements in a group that map to the identity element in a second group under the homomorphism. The video also contain the proofs to show that the kernel is a normal subgroup.

The Kernel of a Group Homomorphism – Abstract Algebra
The kernel of a group homomorphism measures how far off it is from being one-to-one (an injection). Suppose you have a group homomorphism f:G → H. The kernel is the set of all elements in G which map to the identity element in H. It is a subgroup in G and it depends on f. Different ho

Definition of a Subgroup and Proof that the Kernel is a Subgroup
We define what it means for H to be a subgroup of G and give clear criteria which you can follow in order to prove that a given subset is a subgroup. Then we prove that the kernel of f is a subgroup of G. I hope this helps someone learning abstract algebra. Useful Math Supplies https://am

Definition of the Kernel of a Group Homomorphism and Sample Proof
Let f be a group homomorphism from G into H. We define the kernel of f as kerf = {x in G | f(x) = e_H} where e_H is the identity in H. Thus is x is in kerf then we have f(x) = e_H. We prove that if the kernel of f contains only the identity element of G, then f must be an injective functio
