Here, existence and uniqueness of solutions to such problems is shown by a direct method using this principle.</abstract>      <RIV>BA</RIV>   <department>MTR</department>    <permalink>http://hdl.handle.net/11104/0130604</permalink>   <ID_orig>UTIA-B 20000231</ID_orig>     <arlyear>2000</arlyear>       <unknown tag="mrcbU63"> Advances in Mathematical Sciences and Applications Roč. 10 č. 99 2000 57 65 </unknown> </cas_special> </bibitem>
