However, since these functions have not an explicit formula in the time domain, the di‰culty of integrations often occurs. In this paper, we introduce the Galerkin method with Deslauriers–Dubuc interpolating scaling functions, and we use the biorthogonality of the wavelets to overcome the di‰culties of in-tegration. We present numerical results that show the e‰ciency and accuracy of this method.","PeriodicalId":44321,"journal":{"name":"Tsukuba Journal of Mathematics","volume":"37 1","pages":"321-337"},"PeriodicalIF":0.7,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67828953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we investigated the exponent of Hölder-right continuity in case that the motion process is absorbing a-stable motion on ð0;yÞ with 0 < a < 2, that is, time-changed absorbing Brownian motions on ð0;yÞ by the increasing a=2-stable Lévy processes. In the present paper we shall extend the results to the case of simple interactive infinite Markov particle systems. We also consider the absorbing stable motion on a half space H 1⁄4 R 1 ð0;yÞ as a motion process. 1. Settings and Previous Results In this section we give the general settings and the known results which are given in [2] in order to describe the main results in § 3 and § 4. Let S be a domain of R .

For convenience, we fix an extra point D B S and set wðtÞ 1⁄4 D if tb zðwÞ. Moreover we shall extend functions f on S to on fDg by f ðDÞ 1⁄4 0, if necessary.
