(a) Show that there are, up to isomorphism, exactly 8 matroids whose underlying set has three elements. Calling the elements a,b,c, exhibit, for each of these matroids, its bases, cycles and independent sets.
(b) Consider the matroid M on the set E = {a,b,c,d}, where the bases are the subsets of E having precisely two elements. Detrmine all the cycles of M, and show that there is no graph G such that M is the cycle matroid M(G).

using theorem 11.10 (First Isomorphism Theorem), Show that the
set of positive real numbers with multiplication is isomorphic to
the set of real numbers with addition.
Theorem 11.10 First Isomorphism Theorem. If ψ : G → H is a group
homomorphism with K = kerψ, then K is normal in G. Let ϕ : G → G/K
be the canonical homomorphism. Then there exists a unique
isomorphism η : G/K → ψ(G) such that ψ = ηϕ.

(b) State the steps to find an absolute minimum and maximum.
(c) Is the space closed and bounded? Explain.
(d) Use Lagrange Multipliers to find the minimum and maximum

Use a three-period CRR binomial model (meaning three jumps total
up or
down in the underlying) to price a European call option for a
stock whose
share price today is S = 16 when the interest rate is r = 4%,
the maturity
date is 6 months (so T = .5 in years), the strike price is K =
