A brief survey on local holomorphic dynamics in higher dimensions
, 2015 We give a brief survey on local holomorphic dynamics in higher dimensions. The main novelty of this note is that we will organize the material by the "level" of local invariants rather than the type of maps.Comment: 10 pages, to appear in the Proceedings

Minimal generating and separating sets for O(3)-invariants of several matrices
, 2018 Given an algebra $F[H]^G$ of polynomial invariants of an action of the group $G$ over the vector space $H$, a subset $S$ of $F[H]^G$ is called separating if $S$ separates all orbits that can be separated by $F[H]^G$. A minimal separating set is found for

Stable concordance of knots in 3-manifolds
, 2008 Knots and links in 3-manifolds are studied by applying intersection invariants to singular concordances. The resulting link invariants generalize the Arf invariant, the mod 2 Sato-Levine invariants, and Milnor's triple linking numbers.

Generic separation for modular invariants
For modular indecomposable representations of a cyclic group $G$ of prime order $p$ we propose a list of polynomial invariants of degree $\leq 3$ that, together with a simple invariant of degree $p$, separate generic orbits and generate the field of rational invariants. A similar result is proven for decomposable representations of $G$.

The invariant Π⁰_{𝛼} separation principle [PDF]
Transactions of the American Mathematical Society, 1978 We “invariantize” the classical theory of alternated unions to obtain new separation results in both invariant descriptive set theory and in infinitary logic. Application is made to the theory of definitions of countable models.

Separating invariants and finite reflection groups
Advances in Mathematics, 2009 This paper introduces the notion of a geometric separating algebra, for distinguishing between the orbits of a group on some geometric or algebraic space. Given a representation of a group \(G\) on some finite-dimensional space \(V\) over a field \(k\), let \(k[V]\) be the symmetric algebra on the vector space dual of \(V\), and let \(k[V]^G\) be the ...

Synthesising Functional Invariants in Separation Logic [PDF]

Separating Invariants of Finite Groups
, 2016 This thesis studies separating invariants of finite algebraic groups acting on affine varieties through automorphisms. We investigate the question: what restrictions does the existence of a separating set of small size, or a separating algebra with interesting structural properties impose on the group action.
