Regional Fauna

A catalog of aquatic and semiaquatic Heteroptera of the northwest Caucasus is provided based on literature reports and field collections. Representatives of 50 species of the infraorders Nepomorpha and Gerromorpha are listed and are distributed in 11 families, including Aphelocheiridae (1 genus, 1 species), Corixidae (6 genera, 23 species), Gerridae (3 genera, 9 species), Hebridae (1 genus, 2 species), Hydrometridae (1 genus, 2 species), Mesoveliidae (1 genus, 1 species), Naucoridae (1 genus, 1 species), Nepidae (2 genera, 3 species), Notonectidae (2 genera, 4 species), Pleidae (1 genus, 1 species) and Veliidae (2 genera, 3 species). Five species listed for the fauna of the northwest Caucasus are doubtful. Types of ranges of all species are given. Zoogeography of the regional fauna is discussed.

William More Gabb [1839–1878] described 1163 fossil invertebrate taxa: Protozoa [1 species], Porifera [1 genus, 2 species], Cnidaria [12 species], Bryozoa (with G.H. Horn) [1 family, 8 genera, 67 species], Brachiopoda [15 species], Annelida [7 species], Mollusca [Bivalvia: 15 genera, 2 subgenera, 412 species; Gastropoda: 1 family, 2 subfamilies, 42 genera, 8 subgenera, 489 species; Scaphopoda: 10 species; Cephalopoda: 1 family, 3 genera, 51 species], Arthropoda [Crustacea: 2 species; Cirripedia 1 species], and Echinodermata [11 species]. Listed herein are all fossil taxa named by Gabb, type localities, institutional depository, and remarks concerning current taxonomic status, when known. An annotated list of Gabb’s fossil references is also included. Also listed herein are 134 fossil invertebrate taxa and 33 living mollusk taxa named for him.

Cabling Conjecture

We apply results from both contact topology and exceptional surgery theory to study when Legendrian surgery on a knot yields a reducible manifold. As an application, we show that a reducible surgery on a non-cabled positive knot of genus$g$must have slope$2g-1$, leading to a proof of the cabling conjecture for positive knots of genus 2. Our techniques also produce bounds on the maximum Thurston–Bennequin numbers of cables.

Ramanujan Conjecture

The Saito–Kurokawa lifting of automorphic representations from PGL(2) to the projective symplectic group of similitudes PGSp(4) of genus 2 is studied using the Fourier summation formula (an instance of the "relative trace formula"), thus characterizing the image as the representations with a nonzero period for the special orthogonal group SO(4, E/F) associated to a quadratic extension E of the global base field F, and a nonzero Fourier coefficient for a generic character of the unipotent radical of the Siegel parabolic subgroup. The image is nongeneric and almost everywhere nontempered, violating a naive generalization of the Ramanujan conjecture. Technical advances here concern the development of the summation formula and matching of relative orbital integrals.
