- W4299801887 abstract "This thesis proposes a combinatorial generalization of a nilpotent operator on a vector space. The resulting object is highly natural, with basic connections to a variety of fields in pure mathematics, engineering, and the sciences. For the purpose of exposition we focus the discussion of applications on homological algebra and computation, with additional remarks in lattice theory, linear algebra, and abelian categories. For motivation, we recall that the methods of algebraic topology have driven remarkable progress in the qualitative study of large, noisy bodies of data over the past 15 years. A primary tool in Topological Data Analysis [TDA] is the homological persistence module, which leverages categorical structure to compare algebraic shape descriptors across multiple scales of measurement. Our principle application to computation is a novel algorithm to calculate persistent homology which, in certain cases, improves the state of the art by several orders of magnitude. Included are novel results in discrete, spectral, and algebraic Morse theory, and on the strong maps of matroid theory. The defining theme throughout is interplay between the combinatorial theory matroids and the algebraic theory of categories. The nature of these interactions is remarkably simple, but their consequences in homological algebra, quiver theory, and combinatorial optimization represent new and widely open fields for interaction between the disciplines." @default.
