zbMATH — the first resource for mathematics

Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".
au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.
Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.
"Quasi* map*" py: 1989 The resulting documents have publication year 1989.
so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14.
"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic.

Summary: In 1983 E. S. Lander published “Symmetric designs: An algebraic approach”; see [Lond. Math. Soc. Lect. Note Ser. 74 (1983; Zbl 0502.05010)]. At the back are provided a set of tables. Each entry in a table specifies an abelian group G, the parameters of a putative difference set D in G with cardinality k, whether D exists or not, a construction when D does exist, and a nonexistence proof when D does not exist. At time of publication there were some 25 entries which were open, i.e. the existence or nonexistence of D had not been determined. From 1983 until 1993 K. T. Arasu and others filled in all but 8 entries. In 1994 entry 148 was filled in by J. E. Iiams, R. A. Liebler and K. W. Smith. In this paper we fill in the last seven entries by demonstrating nonexistence. We point out several applications to nonabelian difference sets.
