A general existence principle for strong solutions to the dirichlet problem for the equation δ u + f(t, u) = 0
(Elsevier BV, 1997-05-01)
An existence principle is established for Delta u + f(t, u) = 0 on Omega, u = 0 on partial derivative Omega. Our theory relies on a fixed point result for weakly sequentially continuous and weakly compact maps.
Fixed-point theory for the sum of two operators
(Elsevier BV, 1996-01-01)
We extend a fixed-point theorem of Reinermann [1] for the sum of two operators. Our results are then used to establish new existence results for differential equations in Banach spaces.
Genetic structure of neisseria gonorrhoeae populations: a non-clonal pathogen
(Microbiology Society, 1993-11-01)
Reproduction by binary fission generates a clonal genetic structure in bacterial populations in the absence of a high rate of recombination. The extent of recombination in natural populations of Neisseria gonorrhoeae was ...
On the relationship between monstrous moonshine and the uniqueness of the moonshine module
(Springer Nature, 1995-01-01)
We consider the relationship between the conjectured uniqueness of the Moonshine Module, V-h, and Monstrous Moonshine, the genus zero property of the modular invariance group for each Monster group Thompson series. We first ...
Small subunit rrna gene sequences of aeromonas salmonicida subsp. smithia and haemophilus piscium reveal pronounced similarities with a. salmonicida subsp. salmonicida
(Inter-Research Science Center, 1999-01-01)
The small subunit ribosomal RNA (SSU rRNA) encoding genes from reference strains of Aeromonas salmonicida subsp, smithia and Haemophilus piscium were amplified by polymerase chain reaction and cloned into Escherichia coli ...
On the palaeogeography of baltica during the palaeozoic: new palaeomagnetic data from the scandinavian caledonides
(Oxford University Press (OUP), 1990-10-01)
Delayed profound respiratory depression after premedication with trimeprazine
(Wiley-Blackwell, 1992-07-01)
Multiwavelength observations of a flare from markarian 501
(IOP Publishing, 1997-10-01)
We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very high energy (VHE; E greater than or similar ...
Phage inhibition, colicin resistance, and tellurite resistance are encoded by a single cluster of genes on the inchi2 plasmid r478.
(American Society for Microbiology, 1995-09-01)
A region of the IncHI2 plasmid R478, encoding the phenotypes of tellurite resistance (Te-r), phage inhibition (Phi), and colicin resistance (PacB), was cloned and sequenced. Analysis indicated seven open reading frames ...
