This theorem links two fundamental concepts of Mathematics, truth and provability, and provides deep insights into ways of mathematical thinking. Prospective students should enjoy abstract ideas and have the ability to understand mathematical proofs of the type which occur in Pure Mathematics.

I shall review the problem for three languages: PCF (the original problem), PCF + control, and an ALGOL-like language. The sequential algorithms and the games models have provided satisfactory (effective) solutions for the latter two languages, respectively, while the identification of the constraints that tailor the games model to just PCF was the key to a very interesting classification known as Abramsky's ``semantic cube".

CSE 291 Lecture Notes, October 9, 2002
Theorem LehmannScheffe Suppose t(x) is a complete sufficient statistic fortheta, Use the completeness theorem for an exponential family.
http://www-cse.ucsd.edu/users/elkan/291/oct9.html

Extractions: October 9, 2002 I would like people to use the discussion boards to ask questions about the lectures and the first assignment. Remember, the assignment is due one week from now. You are welcome to work in study groups, but each student should write up his/her answers independently. See the October 7 lecture notes for books recommended as background reading. I'll describe this algorithm as a theorem. So E[ g hat(t) - g bar(t) ] = for every theta. By completeness g hat(t) - g bar(t) = for all t, so g hat and g bar are the same. So the Rao-Blackwell process always gives the same improved estimator, regardless of which crude estimator we begin with. Algorithm: Instead of steps 3 and 4, sometines you can directly guess some g bar(t) and prove that it is unbiased. Steps 1 and 2 only have to be done once for a given family of distributions P_theta. They can then be reused for different estimation targets g(theta). How do you do step (1)? Use the factorization theorem.

http://www.math.uiuc.edu/ResearchAreas/logic/courses.html

Extractions: The starting point, and a distinctive feature of mathematical logic, is the introduction of suitable formal languages. For assertions (sentences) in such a language, key notions are "provability" and "truth". To formulate a formal system for proving sentences requires the introduction of axioms and rules of inference. Truth of sentences depends on fixing a universe of discourse and appropriate meanings for the special symbols in the language. In our introductory courses (Math 414 at the undergraduate level and Math 570 at the graduate level) we set up this basic framework for first-order logic, and study the fundamental and sometimes surprising connections between provability and truth. Mathematical logic is traditionally seen as being roughly composed of four main areas: model theory, computability theory, set theory, and proof theory. The first three of these areas are represented in our group and are covered extensively in the graduate courses that we offer above Math 570. Discussion of Courses Two introductory courses (Math 414 and Math 570) are offered in logic. Math 414 is primarily for undergraduates. Math 570 is a prerequisite for all other graduate courses in logic and is also the best course for a graduate student who wants to take a single semester of logic. Math 570 is one of the basic courses in the Comprehensive Exams system of the PhD program in the UIUC Department of Mathematics. Students who have had a course similar to Math 570 elsewhere and wish to go directly into other graduate logic courses should consult a faculty member in logic to be sure that they have the necessary prerequisites.

http://www.math.uwaterloo.ca/~snburris/htdocs/LMCS/preface.html

Extractions: Mathematical logic has been, in good part, developed and pursued with the hope of providing practical algorithmic tools for doing reasoning, both in everyday life and in mathematics, first by hand or mechanical means, and later by electronic computers. In this text elementary traditional logic is presented side by side with its algorithmic aspects, i.e., the syntax and semantics of firstorder logic up to completeness and compactness, and developments in theorem proving that were inspired by the possibilities of using computers. Here we are referring to Robinson's resolution theorem proving, and to the KnuthBendix procedure to obtain term rewrite systems, both using the key idea of (most general) unification. Thus we find the choice of topics important as well as accessible to a wide range of students in the mathematical sciences. These topics are rich in basic algorithms, giving the students a desirable hands-on experience. No background in abstract algebra or analysis is assumed, yet the material is definitely mathematical logic, logic for mathematics and computer science that is developed and analyzed using mathematical methods.
