We can construct a polynomial-time reduction from q to p as follows: given an instance x of q, run A on x to obtain a solution y, and then run B on f(x, y), where f is the polynomial-time reduction from q to p. The output of B is a solution to f(x, y), which is in p by definition of the reduction. Therefore, p is closed under homomorphism.
To show that p is closed under homomorphism if and only if p = np, we need to prove both directions.
First, assume that p is closed under homomorphism. We want to show that p = np. Suppose for contradiction that there exists a problem q in np that is not in p. Then, there exists a polynomial-time algorithm A that can solve q.
We can construct a polynomial-time reduction from q to p as follows: given an instance x of q, run A on x to obtain a solution y, and then output f(x, y), where f is the polynomial-time reduction from p to q. Since p is closed under homomorphism, f(x, y) is in p, and so x is also in p. But this contradicts the assumption that q is not in p. Therefore, p = np.
Next, assume that p = np. We want to show that p is closed under homomorphism. Let q be any problem in np, and let A be a polynomial-time algorithm that solves q. We need to show that there exists a polynomial-time reduction from q to p. Since p = np, there exists a polynomial-time algorithm B that solves any problem in p.
