i just need A and B part 

1.
(a) Let K CR" be a proper cone. Prove that the relation a – bEK is reflexive, antisymmetric
and transitive on R".
(b) Consider the following two sets of symmetric matrices:
C = {A € S" | x"Ax >0 Vx € R", x>0}
and
k
P = {A € S" | A = E ®(z®)", z® eR", ¿0 > 0, i = 1,...,k} .
i=1
Prove:
(i) C and P are cones.
(ii) Show that C C P*, where P* is the dual cone to P.
(c) Consider the following conic problem in variables (x1,x2) with the Lorentz cone L3:
min { x1 + 2x2||
X2
(P1)
X1+x2
(i) Decide whether the problem is strictly feasible and bounded below. Draw the feasible
region and, if available, find an optimal solution. Find the optimal objective value.
(ii) Formulate the dual problem to (P1).
(iii) Find at least one point in the dual feasible region that is
(1) strictly feasible;
(2) feasible but not strictly feasible.
