However, for i = Gamma1 and 2 n it has been shown [13] that (ln is the natural logarithm) ln(n) ln(n) 1 Gammaln(n) Gamma 1 Gamman Gammaln(n) 13) and also [5] that 2 = 1:65. Based on this approximation it can be shown that for all i 2 the following holds: 2 i , and finally v i 6 if i 2 i 6 if i 2 and i is even i Gamma1 if i 2 and i is odd (14) 11 4.4 Miscellaneous In this section we ....

Now, having de ned the four basic arithmetic operations also for uncertain coecients, Gauss s Elimination Algorithm (see [BS2]) can immediately be applied to linear equations with uncertain coecients. Runtimes have shown to be similar to runtimes obtained for ordinary linear equations. The price for good runtime results is incompleteness of the computational results, due to the incompleteness of naiv interval calculus. ....
