On the Friedlander–Nadirashvili invariants of surfaces
Get PDFLet M be a closed smooth manifold. In 1999, Friedlander and Nadirashvili introduced a new differential invariant I₁ (M) using the first normalized nonzero eigenvalue of the Lalpace–Beltrami operator Δ_g of a Riemannian metric g. They defined it taking the supremum of this quantity over all Riemannian metrics in each conformal class, and then taking the infimum over all conformal classes. By analogy we use k-th eigenvalues of Δ_g to define the invariants I_k(M) indexed by positive integers k. In the present paper the values of these invariants on surfaces are investigated. We show that I_k(M) = Ik(S²) unless M is a non-orientable surface of even genus. For orientable surfaces and k = 1 this was earlier shown by Petrides. In fact Friedlander and Nadirashvili suggested that I₁(M) = I₁ (S²) for any surface M different from RP². We show that, surprisingly enough, this is not true for non-orientable surfaces of even genus, for such surfaces one has I_k(M) > I_k(S²). We also discuss the connection between the Friedlander–Nadirashvili invariants and the theory of cobordisms, and conjecture that I_k(M) is a cobordism invariant
Case of severe Friedlander′s pneumonia with review of the literature
No full textFriedlander′s bacillus (Klebsiella pneumoniae) is among the most common Gram-negative bacteria encountered by physicians world-wide. Here, we report 31 years immunocompetent male who presented with fever, productive cough, hemoptysis, breathlessness and multi-organ failure with radiological evidence of total right upper lobe consolidation. Sputum microscopy, culture and blood culture - all confirmed Friedlander′s bacillus as the etiology of this severe community acquired pneumonia with fatal outcome

On the Friedlander–Nadirashvili invariants of surfaces
Get PDFLet M be a closed smooth manifold. In 1999, L. Friedlander and
N. Nadirashvili introduced a new differential invariant I1(M) using the first normalized nonzero eigenvalue of the Lalpace-Beltrami operator ∆g of a Riemannian
metric g. They defined it taking the supremum of this quantity over all Riemannian metrics in each conformal class, and then taking the infimum over all conformal
classes. By analogy we use k-th eigenvalues of ∆g to define the invariants Ik(M)
indexed by positive integers k. In the present paper the values of these invariants
on surfaces are investigated. We show that Ik(M) = Ik(S
2
) unless M is a nonorientable surface of even genus. For orientable surfaces and k = 1 this was earlier
shown by R. Petrides. In fact L. Friedlander and N. Nadirashvili suggested that
I1(M) = I1(S
2
) for any surface M different from RP2
. We show that, surprisingly
enough, this is not true for non-orientable surfaces of even genus, for such surfaces
one has Ik(M) > Ik(S
2
). We also discuss the connection between the FriedlanderNadirashvili invariants and the theory of cobordisms, and conjecture that Ik(M) is
a cobordism invariant
