Sylow theorems
The Sylow theorems are fundamental results in group theory, a branch of mathematics that studies algebraic structures known as groups. These theorems provide information about the existence and number of p-subgroups within a finite group, where a p-subgroup is a subgroup whose order is a power of a prime number p.
The first Sylow theorem guarantees the existence of at least one p-subgroup for each prime divisor of the group's order. The second theorem describes how many such p-subgroups exist, while the third theorem states that all p-subgroups of a given order are conjugate to each other, meaning they are structurally similar within the group.
