Consider the group homomorphism φ : S3 ×
S5→ S5 and φ((σ, τ )) = τ .
(a) Determine the kernel of φ. Prove your answer. Call K the
kernel.
(b) What are all the left cosets of K in S3×
S5 using set builder notation.
(c) What are all the right cosets of K in S3 ×
S5 using set builder notation.

Given a function φ(z) with z = x+iy let
U(x, y) = ½ [φ(x+iy) + φ(x-iy)] and V(x, y) = i/2
[φ(x+iy) –φ(x-iy)]
A) For φ(z) = z2 find U and V and their induced
vector fields E =▼U and
F =▼V also show that ▼2U =
▼2V = 0
B) Repeat for f(z) = z3
C) For f(z) = ln z we get U(x, y) = ½ ln
(x2+y2) and V(x, y) = arctan (y/x) Find ▼U

Let F be a field and let φ : F → F be a ring isomorphism. Define
Fix φ to be Fix φ = {a ∈ F | φ(a) = a}. That is, Fix φ is the set
of all elements of F that are fixed under φ. Prove that Fix φ is a
field. (b) Define φ : C → C by φ(a + bi) = a − bi. Take
for granted that φ is a ring isomorphism (we...
We mentioned the first fit and best fit as applied to finding
parking spaces at a mall.
a.) Write a first-fit car parking algorithm
b.) Write a best-fit car parking algorithm
c.) In your own words, explain why first fit might be a better
algorithm on average to minimize the time to get to the door of the
mall.
This has to be programmed within Python. Please and thank
you.
