On Safety of Unary and Non-unary IFP-operators
In this paper, we investigate the safety of unary inflationary fixed point operators (IFPoperators). The safety is a computability in finitely many steps.

Around the root of random multidimensional quadtrees [PDF]
We analyse the distribution of the root pattern of randomly grown multidimensional point quadtrees. In particular, exact, recursive and asymptotic formulas are given for the expected arity of the root.

Parametrised Complexity of Model Checking and Satisfiability in Propositional Dependence Logic [PDF]
In this paper, we initiate a systematic study of the parametrised complexity in the field of Dependence Logics which finds its origin in the Dependence Logic of V\"a\"an\"anen from 2007.

Cross-Sentence N-ary Relation Extraction using Lower-Arity Universal Schemas
Most existing relation extraction approaches exclusively target binary relations, and n-ary relation extraction is relatively unexplored. Current state-of-the-art n-ary relation extraction method is based on a supervised learning approach and, therefore,

Dynamic Complexity of Parity Exists Queries [PDF]
Given a graph whose nodes may be coloured red, the parity of the number of red nodes can easily be maintained with first-order update rules in the dynamic complexity framework DynFO of Patnaik and Immerman.

Additive decomposability of functions over abelian groups [PDF]
Abelian groups are classified by the existence of certain additive decompositions of group-valued functions of several variables with arity gap 2.Comment: 17 ...

Essential arities in algebras of finite type and arity trees
Given an algebra \(A\), \(S(A)\) denotes the set of those nonnegative integers \(n\) for which there is a nontrivial essentially \(n\)-ary term operation on \(A\). In 1965, K. Urbanik characterized the sets \(S\) of integers such that \(S= S(A)\) for some idempotent algebra \(A\).

On the Mints Hierarchy in First-Order Intuitionistic Logic [PDF]
We stratify intuitionistic first-order logic over $(\forall,\to)$ into fragments determined by the alternation of positive and negative occurrences of quantifiers (Mints hierarchy). We study the decidability and complexity of these fragments.

CUHK at MRP 2019: Transition-Based Parser with Cross-Framework Variable-Arity Resolve Action
This paper describes our system (RESOLVER) submitted to the CoNLL 2019 shared task on Cross-Framework Meaning Representation Parsing (MRP). Our system implements a transition-based parser with a directed acyclic graph (DAG) to tree preprocessor and a ...
