Unfortunately, generating these complexes is expensive because of a combinatorial explosion in the complex size. For <i>n</i> points in <math> <msup><mrow><mi>R</mi></mrow> <mi>d</mi></msup> </math> , we present a scheme to construct a 2-approximation of the filtration of the Rips complex in the <math><msub><mi>L</mi> <mi>∞</mi></msub> </math> -norm, which extends to a <math><mrow><mn>2</mn> <msup><mi>d</mi> <mrow><mn>0.25</mn></mrow> </msup> </mrow> </math> -approximation in the Euclidean case. The <i>k</i>-skeleton of the resulting approximation has a total size of <math><mrow><mi>n</mi> <msup><mn>2</mn> <mrow><mi>O</mi> <mo>(</mo> <mi>d</mi> <mo>log</mo> <mi>k</mi> <mo>+</mo> <mi>d</mi> <mo>)</mo></mrow> </msup> </mrow> </math> . The scheme is based on the integer lattice and simplicial complexes based on the barycentric subdivision of the <i>d</i>-cube. We extend our result to use cubical complexes in place of simplicial complexes by introducing <i>cubical maps</i> between complexes. We get the same approximation guarantee as the simplicial case, while reducing the total size of the approximation to only <math><mrow><mi>n</mi> <msup><mn>2</mn> <mrow><mi>O</mi> <mo>(</mo> <mi>d</mi> <mo>)</mo></mrow> </msup> </mrow> </math> (cubical) cells. There are two novel techniques that we use in this paper. The first is the use of <i>acyclic carriers</i> for proving our approximation result. In our application, these are maps which relate the Rips complex and the approximation in a relatively simple manner and greatly reduce the complexity of showing the approximation guarantee. The second technique is what we refer to as <i>scale balancing</i>, which is a simple trick to improve the approximation ratio under certain conditions.</p>","PeriodicalId":73600,"journal":{"name":"Journal of applied and computational topology","volume":"5 3","pages":"425-458"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41468-021-00072-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39580559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
