Catalan Tree & Parity of some sequences which are related to Catalan numbers [PDF]

open access: yes, 2011
In this paper we determine the parity of some sequences which are related to Catalan numbers.

Logic and theory of representation

open access: yes, 2023
Underlying the theory of inferences, a primary task of logic is language analysis. Such a task can be understood as depending on a general theory of representation, taking as a starting point the idea that some entities (`` representations '') can ...

Ordered homomorphisms and kernels of ordered BCI-algebras

open access: yes, 2023
Recently Yang-Roh-Jun introduced the notion of ordered BCI-algebras as a generalization of BCI-algebras. They also introduced the notions of homomorphisms and kernels of ordered BCI-algebras and investigated related properties.

Classical model existence and left resolution [PDF]

open access: yes, 2008
By analyzing what are necessary conditions in the proof [4] of the classical model existence theorem CME (every consistent set has a classical model), we present the left resolution Gentzen systems R(¬,-), which proof-theoretically characterize ...

Finding the Nucleoli of Large Cooperative Games: A Disproof with Counter-Example [PDF]

open access: yes, 2016
Nguyen and Thomas (2016) claimed that they have found a method to compute the nucleoli of games with more than 50 players using nested linear programs (LP). Unfortunately, this claim is false.

Calibrating the Complexity of Ternary Propositional Connectives [PDF]

open access: yes, 2017
For each ternary propositional connective, we determine the minimum number of binary connectives needed to construct a logically equivalent formula. In order to reduce this problem to a computably feasible one, we prove a number of lemmas showing that

Resolution and binary decision diagrams cannot simulate each other polynomially [PDF]

open access: yes, 2000
There are many different ways of proving formulas in proposition logic. Many of these can easily be characterized as forms of resolution. Others use so-called binary decision diagrams (BDDs).
