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.
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.
dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles.

Similarity solutions for high frequency excitation of liquid metal in an antisymmetric magnetic field. (English) Zbl 1120.34009
Biler, Piotr (ed.) et al., Self-similar solutions of nonlinear PDE. Selected papers of the conference, Bȩdlewo, Poland, September 5–9, 2005. Warsaw: Polish Academy of Sciences, Institute of Mathematics. Banach Center Publications 74, 41-57 (2006).

The authors consider the third order nonlinear autonomous differential equation

f ''' +m+1 2ff '' -mf ' 2 =0

with the boundary conditions

f(0)=a,f ' (0)=-1,f ' ()=0,

where m and f ' ()=lim t f ' (t). Several existence results are established in both cases m<0 and m>0. The solutions of the above problem are similarity solutions of problems related to the phenomenon of high frequency excitation of liquid metal system in an antisymmetric magnetic field, within the framework of boundary layer approximation.
