Computational Logic Seminar
Time 2:00 – 4:00 PM, March 6, Room 3209
Speaker: Cagil Tasdemir (CUNY)
Title: DKAL and Infon Logic

Abstract: Distributed Knowledge Authorization Language (DKAL) is a
logic-based language for managing policies and trust in distributed
scenarios. In the DKAL world, principals (agents) have their own
states and compute their own knowledge. DKAL is based on a logic of
information called infon logic developed by Gurevich et al. Infons are
declarative statements viewed as pieces of information and can be
communicated from one principal to another. We will present the syntax
and semantics for infon logic and discuss the soundness and
completeness results.

 

Model Theory, Number Theory, Algebraic Geometry Umbrella series

MONTAGU / Spring2012 + Model Theory Seminar / Spring2012
Dr. Ivan Tomasić (Queen Mary, University of London)
A twisted theorem of Chebotarev

Abstract. We will discuss a function field version of a theorem of
Chebotarev describing the distribution of local Frobenius elements
associated with a Galois covering of difference-algebraic varieties.
The result is stated in a shape of a trace formula, and one crucial
ingredient is Hrushovski’s twisted Lang-Weil estimate for the number
of points of a difference variety over the algebraic closure of a
finite field with a power of Frobenius. We will also give a general
description of definable sets over fields with Frobenius in terms of
twisted Galois covers.

MONTAGU is an interdisciplinary seminar organized by Roman Kossak,
Philipp Rothmaler, Hans Schoutens, and Lucien Szpiro
