Computation Logic and Information

Information, computation, and logic are defining concepts of the modern era. Shannon laid the foundation of information theory, demonstrating that problems of communication and compression can be precisely modeled, formulated, and analyzed. Turing formalized computation defined as the transformation of information by means of algorithms.  Godel established modern foundation of logic, laying the foundation for modern computer science and science of information.

Shannon's focus was originally on data recovery in compression and communication, but information is not merely communicated, it is also acquired, represented, inferred, processed, aggregated, managed, valued, secured, and computed.  Computational information explores those properties of information that can be feasibly extracted. Existence of an object is of limited utility if no reasonable algorithm can provably generate such an object.  Infeasibility may arise for a number of different reasons:  the desired information may be computationally hard to extract; the information may be distributed geographically and not locally extractable; or information may be encoded in (quantum) physical ways that prevent full extraction.  In contrast to the classical theory of information, where precise quantitative limits can be established in most cases, in the computational setting, information is not well understood qualitatively, with exponential gaps between the upper and lower bounds on the amount of feasibly extractable information.

We must add logic to this paradigm. At its most basic, logic is the study of consequence. The core intuition motivating including logic in information is that an informational state may be characterized by the range of possibilities or configurations that are compatible with the information available at that state. But logic may restrict range of possibility, directly impacting just information. Furthermore, logic ``unusual effectiveness in computer science'', from descriptive complexity to type theory (including Voevodsky univalent axiom) to reasoning about knowledge closes the loop from logic to information to computation. Understanding how to harness it in order to deepen connections to a theory of information remains very much an open question.

There are plenty of questions with very few satisfying answers: Is there a way to account for the meaning or semantics of information?  Can we construct a theory information that is representation-invariant? What is misinformation?

7th Polish Combinatorial Conference, Będlewo

The Polish Combinatorial Conferences are meant to integrate Polish and international combinatorial communities. The upcoming conference is, as before, dedicated mostly to young scientists whose attendance we strive to support (see below). Having this goal in mind, besides several invited talks, we provide also a couple of tutorials by leading experts in Combinatorics.

The scope of the conference is intended to cover most aspects of modern combinatorics, including graph theory, probabilistic combinatorics, extremal combinatorics, combinatorial optimization, algorithmic problems, combinatorial number theory, applications of combinatorics in computer science.

Order & Geometry Workshop

The workshop will be an informal meeting of around 30 people working in combinatorics and theoretical computer science with special emphasis on discrete geometry, partially ordered sets and all kinds of interplays between them.

This includes: geometric intersection graphs, geometric representations of graphs, point and line arrangements, Schnyder woods and related graph orientations, parameters of partially ordered sets, especially order dimension.

Wykład Wojciecha Szpankowskiego "Analytic Information Theory: From Shannon to Knuth and Back"
Wykład Wydziałowy Analytic information theory 21.06 o godzinie 11:00 w sali 1016

Analytic information theory aims at studying problems of information theory
using analytic techniques of computer science and combinatorics. Following Hadamard's precept, we tackle these problems by complex analysis methods
such as generating functions, Mellin transform, Fourier series, saddle point method, analytic poissonization and depoissonization, and singularity
analysis. This approach lies at the crossroad of computer science and information theory. In this talk, we concentrate on one facet of information theory namely, source coding better known as data compression and present several results illustrating the power of analytic methods.

The talk is dedicated to Don. E. Knuth for his 80th birthday.
