Law of Exponents, Laplace Transform of Fractional Operators, and Fractional
Initial Value Problem (IVP)
(1) In general, the semigroup law does not hold for derivatives of arbitrary order, that is:
Dº Dª Dª D°, DºD³ +D+B
To show that the semigroup law does not hold, in general, for derivatives in the sense of Riemann-
Liouville, calculate the following expressions:
a) (DD) (t);
b) (D+) (+);
c)
(DD) (+);
d) (DD) (t³);
e) (D) (t).
(2) Consider the Laplace transform for the fractional derivative in the sense of
Caputo and the Laplace transform for the fractional derivative in the sense of
Riemann-Liouville, respectively, as given below:
m-1
-1-k
L{.D°f(t); 8} = 8° L{f(t)} -Σs¹ƒ) (0°),
where
and
f(*) (0*) := lim D*ƒ(t);
m-1
-1-k
£{D° f(t); } = 8º£{f(t)} - Σg(*) (0*),
-0
9) (0+) = lim Dƒ(t), where g(t)J("-") ƒ (t).
In both cases, m-1<a<m.
a) Under what conditions are the Laplace transforms of Riemann-Liouville and Caputo the same?
b) What are the expressions for the Laplace transforms when 0 < a <1?
