Relative Framing of Transverse Knots
It is well-known that a knot in a contact manifold (M, C) transverse to a trivialized contact structure possesses the natural framing given by the first of the trivialization vectors along the knot. If the Euler class eC ∈ H (M) of C is nonzero, then C is nontrvivializable and the natural framing of transverse knots does not exist. We construct a new framing-type invariant of transverse knots c...
متن کاملCore Higher-Order Session Processes: Tractable Equivalences and Relative Expressiveness
This work proposes tractable bisimulations for the higher-order πcalculus with session primitives (HOπ) and offers a complete study of the expressivity of its most significant subcalculi. First we develop three typed bisimulations, which are shown to coincide with contextual equivalence. These characterisations demonstrate that observing as inputs only a specific finite set of higher-order valu...
متن کاملOn Monoidal Equivalences and Ann-equivalences
The equivalence between a monoidal category and a strict one has been proved by some authors such as Nguyen Duy Thuan [8], Christian Kassel [2], Peter Schauenburg [7]. In this paper, we show another proof of the problem by constructing a strict monoidal category M(C) consisting of M -functors and M morphisms of a category C and we prove C is equivalent to it. The proof is based on a basic chara...
متن کاملEquivalences in Bicategories
In this paper, we establish some connections between the concept of an equivalence of categories and that of an equivalence in a bicategory. Its main result builds upon the observation that two closely related concepts, which could both play the role of an equivalence in a bicategory, turn out not to coincide. Two counterexamples are provided for that goal, and detailed proofs are given. In par...
متن کاملLissajous Knots and Knots with Lissajous Projections
Knots in R which may be parameterized by a single cosine function in each coordinate are called Lissajous knots. We show that twist knots are Lissajous knots if and only if their Arf invariants are zero. We further prove that all 2-bridge knots and all (3, q)-torus knots have Lissajous projections.
