"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.

Controllability of Volterra-Fredholm type systems in Banach spaces. (English) Zbl 1160.93005
Summary: We show the results in D. N. Chalishajar [J. Franklin Inst. 344, No. 1, 12–21 (2007; Zbl 1119.93016)] and Y.-K. Chang and D. N. Chalishajar [Controllability of mixed Volterra-Fredholm type integro-differential systems in Banach spaces, J. Franklin Inst. 345, 499–507 (2008), doi:10.1016/j.jfranklin.2008.02.002] are only valid for ordinary differential control systems. As a result the examples provided cannot be recovered as applications of the abstract results.
