Critical Two-Point Function for Long-Range Models with Power-Law Couplings: The Marginal Case for d >= d(c)
No full textConsider the long-range models on Z(d) of random walk, self-avoiding walk, percolation and the Ising model, whose translation-invariant 1-step distribution/coupling coefficient decays as |x|(-d-alpha) for some alpha > 0. In the previous work (Chen and Sakai in Ann Probab 43:639-681, 2015), we have shown in a unified fashion for all alpha not equal 2 that, assuming a bound on the "derivative" of the n-step distribution (the compoundzeta distribution satisfies this assumed bound), the critical two-point function G(pc) (x) decays as |x|(alpha boolean AND 2-d) above the upper-critical dimension d(c) = (alpha boolean AND 2)m, where m = 2 for self-avoiding walk and the Ising model and m = 3 for percolation. In this paper, we show in a much simpler way, without assuming a bound on the derivative of the n-step distribution, that G(pc) (x) for the marginal case alpha = 2 decays as |x|(2-d)/ log |x| whenever d >= d(c) (with a large spread-out parameter L). This solves the conjecture in Chen and Sakai (2015), extended all the way down to d = d(c), and confirms a part of predictions in physics (Brezin et al. in J Stat Phys 157:855-868, 2014). The proof is based on the lace expansion and new convolution bounds on power functions with log corrections

This species occupies the southern part of Kyushu; in this region it is well known as a pest of shiitake mushrooms.Published as part of Osada, Yohei, Sakai, Makoto & Hirowatari, Toshiya, 2015, A revision of the genus Morophagoides Petersen (Lepidoptera, Tineidae) from Japan, pp. 351-368 in Zootaxa 3973 (2) on page 359, DOI: 10.11646/zootaxa.3973.2.9, http://zenodo.org/record/23748
Correct Bounds on the Ising Lace-Expansion Coefficients
No full textThe lace expansion for the Ising two-point function was successfully derived in (Sakai in Commun Math Phys 272:283-344, 2007, Proposition 1.1). It is an identity that involves an alternating series of lace-expansion coefficients. In the same paper, we claimed that the expansion coefficients obey certain diagrammatic bounds which imply faster x-space decay (as the two-point function cubed) above the critical dimension d(c) (= 4 for finite-variance models) if the spin-spin coupling is ferromagnetic, translation-invariant, summable and symmetric with respect to the underlying lattice symmetries. However, we recently found a flaw in the proof of (Sakai in Commun Math Phys 272:283-344, 2007, Lemma 4.2), a key lemma to the aforementioned diagrammatic bounds. In this paper, we no longer use the problematic (Sakai 2007, Lemma 4.2), and prove new diagrammatic bounds on the expansion coefficients that are slightly more complicated than those in (Sakai 2007, Proposition 4.1) but nonetheless obey the same fast decay above the critical dimension d(c). Consequently, the lace-expansion results for the Ising and phi(4) models in the literature are all saved. The proof is based on the random-current representation and its source-switching technique of Griffiths, Hurst and Sherman, combined with a double expansion: a lace expansion for the lace-expansion coefficients

Carapace globose (Figs. 1B, 2B, 3B); dorsal surface appears almost smooth or with very low granules (Fig. 3B); branchial regions not distinctly swollen laterally and dorsally, lateral margin of carapace smooth (Fig. 3B); dome-shape in frontal view (Fig. 4C); frontal region protruding anteriorly with buccal cavity and third maxillipeds not visible in dorsal view, frontal lobes distinctly triangular (Fig. 3B); outer surface of third maxillipeds almost smooth or with low, flattened granules (Figs. 4C, D, 5D, E); exopod of third maxilliped in adult broad but not foliaceous (Fig. 5D, E); surfaces of ambulatory legs and chelipeds completely smooth (Figs. 1B, 2B, 6B); G1 very elongate, distal part slightly flared, subdistal lateral projection dorso-ventrally flattened (Fig. 8 E–H); female sternopleonal cavity without projection between vulvae (Fig. 9D). Western Pacific. Remarks. Sakai (1961) described the species from three male and two female specimens from Tosa Bay in Japan. The depository for this material was not specified and it is not known where they are now (see remarks for Neparilia tuberculata below). The species, however, is very distinct and there is now no doubt about its identity. Uncertainties about the presence of P. major in the Indian Ocean by Sakai (1961) and Tirmizi & Serène (1971) are clarified in this paper with the discovery that this material actually belongs to a new species, P. pattersoni (see remarks for this species below). Distribution. Has been reported from Japan and the East China Sea (Sakai, 1961, 1976; Takeda, 1993; Ikeda, 1998; Marumura & Kosaka, 2003), mainland China (Chen & Sun, 2002), Taiwan (Tan et al., 2000; Ng et al., 2001; Chen & Sun, 2002), Philippines (Chen, 1989; Tan, 1996; Galil & Ng, 2007) to Makassar (Indonesia) (Chen, 1990) Papua New Guinea (Galil & Ng, 2015) and Solomon Islands (Galil, 2007). The species occurs at depths between 100–457 m (Alcock, 1899; Chen, 1989; Galil, 2015).Published as part of Ng, Peter K.
