... 13, 1994. Abstract. Bounds on the number of simple zeros of the derivatives of a function are used to give bounds on the number of distinct zeros of the function. The Riemann ξ-function is defined ... generically, the left side of (7) equals N (j) s (T ). In other words, the zeros of the derivatives of a generic function are all simple, except for thos...

... proves the lemma. We now need to establish a similar result to the one stated in the previous lemma inthecasewhereA ∗ is obtained from A by replacing sets of A by sets in their new- shade. The proofs ... The proofs of the following lemmas are similar to the proof of Lemma 4 and we shall try to keep them as short as possible. We need to discuss the cases n odd and n e...

This investigation is particularly interesting for H spanning n and containing no collinear vectors. Our ... contains no collinear vectors, simp(H) is minimal if and only if H is contained in two planes intersecting in H, one of contains exactly three vectors of H; i.e. precise...
