In this paper we construct a generating family quadratic at infinity for any exact Lagrangian in $mathbb{R}^{2n}$ equal to $mathbb{R}^n$ outside a compact set. Such generating families are related to the space $mathcal{M}_infty$ considered by Eliashberg and Gromov. We show that this space is the homotopy fiber of the Hatcher-Waldhausen map, and thus serves as a geometric model for this space. This relates the understanding of exact Lagrangians (and Legendrians) to algebraic K-theory of spaces. We then use this fibration sequence to produce new results (restrictions) on this type of Lagrangian. In particular we show how Bokstedts result that the Hatcher-Waldhausen map is a rational homotopy equivalence proves the new result that the stable Lagrangian Gauss map for our Lagrangian relative infinity is homotopy trivial.
We show that the transfer map on Floer homotopy types associated to an exact Lagrangian embedding is an equivalence. This provides an obstruction to representing isotopy classes of Lagrangian immersions by Lagrangian embeddings, which, unlike previou
Suppose one has found a non-empty sub-category $mathcal{A}$ of the Fukaya category of a compact Calabi-Yau manifold $X$ which is homologically smooth in the sense of non-commutative geometry, a condition intrinsic to $mathcal{A}$. Then, we show $math
We prove that existence of a k-rational point can be detected by the stable A^1-homotopy category of S^1-spectra, or even a rationalized variant of this category.
It is known by results of Dyckerhoff-Kapranov and of Galvez--Carrillo-Kock-Tonks that the output of the Waldhausen S.-construction has a unital 2-Segal structure. Here, we prove that a certain S.-functor defines an equivalence between the category of
In a previous paper, we showed that a discrete version of the $S_bullet$-construction gives an equivalence of categories between unital 2-Segal sets and augmented stable double categories. Here, we generalize this result to the homotopical setting, b
