The d-bar-Neumann operator and the Kobayashi metric
No full textWe study the ���-Neumann
operator and the Kobayashi metric. We observe that under certain
conditions, a higher-dimensional domain fibered over �� can
inherit noncompactness of the d-bar-Neumann
operator from the base domain ��. Thus we have a domain
which has noncompact d-bar-Neumann operator but
does not necessarily have the standard conditions which usually
are satisfied with noncompact d-bar-Neumann operator.
We define the property K which is related to the Kobayashi metric and gives
information about holomorphic structure of fat subdomains. We
find an equivalence between compactness of the d-bar-Neumann operator and the property K in any convex domain.
We also find a local property of the Kobayashi metric [Theorem IV.1], in
which the domain is not necessary pseudoconvex.
We find a more
general condition than finite type for the local regularity of the
d-bar-Neumann operator with the vector-field
method. By this generalization, it is possible for an analytic
disk to be on the part of boundary where we have local
regularity of the d-bar-Neumann operator. By Theorem V.2, we show that an isolated infinite-type point in the
boundary of the domain is not an obstruction for the local
regularity of the d-bar-Neumann operator

Kobayashi pseudometric on hyperkahler manifolds
No full textThe Kobayashi pseudometric on a complex manifold M is the maximal
pseudometric such that any holomorphic map from the Poincaré
disk to M is distance-decreasing. Kobayashi has conjectured that this
pseudometric vanishes on Calabi-Yau manifolds. Using ergodicity of
complex structures, we prove this result for any hyperk¨ahler manifold
if it admits a deformation with a Lagrangian fibration, and its Picard
rank is not maximal. The SYZ conjecture claims that any parabolic
nef line bundle on a deformation of a given hyperkähler manifold is
semi-ample. We prove that the Kobayashi pseudometric vanishes for
all hyperkähler manifolds satisfying the SYZ property. This proves the
Kobayashi conjecture for K3 surfaces and their Hilbert schemes

Bar scale= 10mm. Photos by Shipher Wu. Diagnosis. This species is related to the Japanese species P. nohirae (Matsumura, 1920). In external appearance, P. rufula can be distinguished from P. nohirae by its more reddish brown coloration and by showing a more distinct forewing discal spot. Male genitalia differences are mentioned in Kobayashi (1994). The female genitalia of P. rufula, when compared with European examples of P. plumigera (Denis & Schiffermüller, 1775) illustrated in Shintlmeister (2008: fig. 1553), do not show a pair of prominent processes on ostium bursae, but instead exhitit a smoothly transverse posterior margin. Description of female (Figs 10; 21). Wingspan 39–40 mm (n= 3). Eye large; antenna dark brown, filiform. Head, thorax and abdomen covered with hair-like chestnut-brown scales. Forewing elongate, chestnut-brown, semi-transparent, apex and tornus rounded; discal spot pale, chestnut brown, elliptical; postmedial line faint, slightly serrate; scales of fringe long, chestnut-brown. Hindwing light grey fringed with chestnut-brown, triangular, apex and tornus rounded; discal spot small, chestnut brown. Female genitalia—Ovipositor lobes membranous with short hair-like setae; both pairs of apophyses long and thin; ostium bursae sclerotized, posterior margin transverse; ductus bursae as long as posterior apophyses, basal portion sclerotized and curved, remainder membranous; corpus bursae membranous, small and sac-like. Distribution and bionomics. This species occurs at mid-altitudes in the broad-leaf primary forest of North and Central Taiwan where Acer hostplans such as A. morrisonense Hayata, A. kawakamii Koidzumi, A. serrulatum Hayata (Aceraceae) are abundant. The adults are univoltine, flying in December.Published as part of Wu, Shipher, Owada, Mamoru & Fu, Chien-Ming, 2013, Rediscovery of two rare ptilodontines in Taiwan: Himeropteryx yui Okano, 1969 stat. nov. and Ptilophora rufula Kobayashi, 1994 (Lepidoptera, Notodontidae), pp. 193-197 in Zootaxa 3702 (2) on pages 194-197, DOI: 10.11646/zootaxa.3702.2.8, http://zenodo.org/record/21808
