Nearly conservative multivalue methods for separable Hamiltonian problems
No full textThis talk investigates the canonical properties of general linear methods for long time integration of Hamiltonian problems. It is known that
the classical symplecticity property is important for the accurate numerical solution of Hamiltonian problems and this is only possible for "canonical"
Runge-Kutta methods. Even if general linear methods cannot be symplectic (see [3]), it is possible to lead them inherit a nearly canonical behavior
from their nonlinear stability properties. This is done by imposing a further algebraic constraint on their coecient matrices, known as G-symplecticity
[1], which is a rst requirement to obtain an accurate conservation of the invariants of an Hamiltonian problem. Special attention will be given to the
numerical treatment of separable Hamiltonian problems: to this purpose, the family of G-symplectic partitioned general linear methods is introduced [2]. Due to their multivalue nature, partitioned general linear methods generate parasitic components of the numerical solution which needs to be properly removed: we discuss how G-symplectic partitioned general linear methods free from parasitism can be constructed. We also consider the eects of G-symplecticity on the order of convergence of the derived methods, by exploiting the theory of B-series. Numerical experiments on a selection of separable Hamiltonian problems are discussed. This is a joint work with J. C. Butcher from the University of Auckland
(New Zealand). [1] J. C. Butcher 2008 Numerical methods for Ordinary Dierential Equations, Second Edition, Wiley. [2] J. C. Butcher, R.

Remaining part of left antenna with 38 flagellomeres; 1 st flagellomere approximately 1.2 × longer than wide and 1.2 × longer than the 2 nd and 3 rd separately. Eyes very large, sharply and deeply emarginated opposite antennal sockets; width of head: width of face: height of eye = 3.5:1.0: 2.3. Face irregularly rugulose.

Mesosoma 1.67 × longer than high. Mesoscutum coriaceous becoming rugulose posteriorly between weakly indicated notauli. Scutellar sulcus wide. Mesopleuron and mesosternum largely shiny with punctures at base of setae, with some fine striation dorsally and near episternal scrobe; precoxal sulcus not impressed nor indicated by change in sculpturation. Propodeum rugulose, with complete but weak and irregular midlongitudinal carina. Fore wing. Lengths of veins r-rs: 3 RSa: 3 RSb = 1.0: 1.5: 4.1. Veins 1 -M and m+cu approximately equal in length and each slightly longer than (RS+M)b. Subbasal cell with strongly enlarged, ovoid apical part, demarked basally by a tubular cross-vein running posteriorly from M+CU to approximately half way across the cell; swollen part with small medial sclerome, largely setose except for quadrant antero-distal to sclerome. Vein 1 cu-a strongly curved and distally expanded. Hind wing. Vein M+CU 1.15 x 1 M. Vein m-cu entirely absent. Vein R more or less interstitial. Lengths of fore femur: tibia: tarsus = 1.0: 1.05: 1.05. Lengths of hind femur: tibia: tarsus = 1.0: 1.15:1.0. Hind femur robust 4.5 × longer than maximally deep. Claws with two strong pectin spines.

Ochreous yellow, stemmaticum black, posterior metasomal tergites piceous. Wing venation pale brown but pterostigma (except extreme base), vein r-rs and veins forming the swollen distal part of the fore wing subbasal cell dark brown. Etymology. Name based on the type locality. Notes. The new species keys easily in Butcher & Quicke (2011) to couplet 16 which leads to three species (A. (H.) plurivena Butcher & Quicke, glandularis Butcher & Quicke and sharkeyi Butcher & Quicke) that have a spur running posteriorly from fore wing vein M+CU demarking the basal end of the swollen part of the subbasal cell, and is clearly most closely related to A. (H.) plurivena in that the spurious transverse vein is tubuar, the precoxal sulcus absent, strongly striate axillae and very large eyes and ocelli. It can easily be separated from this and other species of the subgenus by its far more swollen distal part of the subbasal cell which is more than twice as high as the first subdiscal cell, by the differentiated distal part of fore wing vein M+CU greater than 0.65 x the length of the unmodified basal part as opposed to being at most 0.42 x in other Afrotropical species, and by the glabrous part of the subbasal cell being limited to the part anterodistal to the sclerome.Published as part of Butcher, Buntika A. & Quicke, Donald L.
