Examples

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.

On characteristic function of a meromorphic function and its derivative. (English) Zbl 0799.30018

Indian J. Math. 33, No. 2, 119-133 (1991).

Summary: In this paper relations between \(T(r,f)\) and \(T(r,f^{(k)})\) have been obtained. The results generalize and improve some theorems given by S. M. Shah,S. K. Singh, A. Edrei, V. N. Kulkarni, and H. S. Gopalakrishna.
