Consider the Tragedy of the Commons game from the chapter with two shepherds, A and B, where sA and sB denote the number of sheep each grazes on the common pasture. Assume that the benefit per sheep (in terms of mutton and wool) equals 500-sA-sB implying that the total benefit from a flock of sA sheep is sA(500-sA-sB) and that the marginal benefit of an additional sheep (which is defined by the first partial derivative with respect to sA of the total benefit function) is 500-2sA-sB. Assume that the marginal cost of grazing sheep is 100.

1. Compute the flock sizes and shepherds’ total benefit in the Nash equilibrium.

2. Draw the best-response unction diagram corresponding to your solution.

3. Suppose A’s benefit per sheep drops to 450-sA-sB, which means that his marginal benefit becomes 450-2sA-sB. B’s benefit per sheep does not change. Compute the new Nash equilibrium flock sizes. Show the change from the original to the new Nash equilibrium in your best-response function diagram.

Determine if each of the following statements is true or false. If it’s true, explain why. If it’s false explain why not, or simply give an example demonstrating why it’s false. (A correct choice of “T/F” with no explanation will not receive any credit.)

(a) If a system has more equations than variables, its RREF must have a row of 0’s.

(b) If a consistent system has more variables than equations, then it must have infinitely many solutions.

(c) Consider a system with m equations, n variables, and rank r. If the system has a unique solution, then m = n.

Q. EXPLAIN COLLEY METHOD AND GIVE EXAMPLE?

Required: Formulate and solve the LP Relaxation of the problem. Solve it graphically, and round down to find a feasible solution.

Prove that a continuous function for sections(subrectangles) is integrable in R^N

In the proof of bolzano-weierstrass theorem in R^n on page 56 of "Mathematical Analysis" by Apostol, should the inequality be a/2^(m-2) < r/sqrt(n) or something related to n? a/2^(m-2) < r/2 seems not enough

Consider the following linear operator: L u = d^2u/dx^2+ 2 du/dx + u.

Consider the eigenvalue problem L u + λu = 0, x ∈ (0, π), u(0) = 0, u(π) = 0.

(a) Determine the possible eigenvalues and eigenfunctions.

(b) Use an integrating factor to put the eigenvalue problem in Sturm-Liouville form.

(c) What is the appropriate inner product for this system?

Show that, for each value of n, the graph associated with the alcohol C_nH_2n+1OH is a tree (the oxygen vertex has degree 2). Draw the tree corresponding to the molecule C₂H₅OH.

Do the following numbers have a finite binary expansion or not:

Construct a ring isomorphism Z2 ⊕Z3 → End(Z2 ⊕Z3)

This is considering the Phi function (The Euler Phi Function)

(a) Explain why φ(m) is always even when m ≥3.

(b) φ(m) is rarely a prime number. Find all numbers m so that φ(m) is prime.

I'm solving for part b. From part a, it looks like there is no prime number for phi of m when it's greater than or equal to 3. Now, I notice that Phi of 4 is 2, Phi of 3 is 2, and Phi of 6 is also 2. It looks like 2 is prime so does that mean m = 3, 4, 6 are all the numbers m in which Phi of m is prime? Please let me know if this is correct or post a solution to what the correct answer is to part b.
