Gilmer* Institute for Advanced Study, Princeton, NJ 08540, USA and Louisiana State University, Baton Rouge, LA 70803, USA Given a knot K in the 3-sphere, the genus of K, denoted g(K), is defined to be the minimal genus for a Seifert surface for K. The slice genus gs(K) is defined ...

WebThe genus Pythium, as currently defined, contains over a hundred species, with most having some loci sequenced for phylogeny [16]. Pythium is placed in the Peronosporales sensu lato, which contains a large number of often diverse taxa in which two groups are commonly recognized, the para- phyletic Pythiaceae, which comprise the basal lineages … WebBy definition the canonical genus of a knot K gives an upper bound for the genus g(K) of K, that is the minimum of genera of all possible Seifert surfaces for K. In this paper, we introduce an operation, called the bridge-replacing move, for a knot diagram which does not change its representing knot type and does not increase the genus of the ...
Weband [L. We say that Determining knot genus in a fixed 3-manifold M is the decision problem asking whether the genus of Kis equal to a given non-negative integer. Theorem 1.2. Let Mbe a compact, orientable 3-manifold given as above. The problem Determining knot genus in the fixed 3-manifold Mlies in NP. 1.1. Ingredients of the proof. Webtheory is the knot Floer homology HFK\(L) of Ozsvath-Szab´o and Rasmussen [7], [15]. In its simplest form, HFK\(L) is a bigraded vector space whose Euler characteristic is the Alexander polynomial. Knot Floer homology is known to detect the genus of a knot [10], as well as whether a knot is fibered [14]. There exists a refinement of HFK ...
