In computability theory, many reducibility relations (also called reductions, reducibilities, and notions of reducibility) are studied. They are motivated by the question: given sets and of natural numbers, is it possible to effectively convert a method for deciding membership in into a method for deciding membership in ? If the answer to this question is affirmative then is said to be reducible to . The study of reducibility notions is motivated by the study of decision problems. For many notions of reducibility, if any noncomputable set is reducible to a set then must also be noncomputable. This gives a powerful technique for proving that many sets are noncomputable.

Vertex Connectivity is Less than or Equal to Minimum Degree | Graph Theory Exercises
The vertex connectivity of every graph is less than or equal to its minimum degree, this is a simple upper bound on vertex connectivity. We prove this fact, and show an example, in today's graph theory video lesson. This inequality is true because if a graph G is disconnected, then its v

Edge Subtraction and Bridges in Graphs | Graph Theory, Edge Deletion
What is edge subtraction in graph theory? How do we delete an edge from a graph? And what is a bridge? That's what we'll be going over in today's video graph theory lesson! When we delete a vertex from a graph we also need to delete the incident edges, but deleting an edge is a bit simple

Lecture 2: The Curry-Howard correspondence
This talk gives an elementary introduction to some central ideas in the theory of computation, including lambda calculus and its relation to category theory. The aim was to get to the statement of the Curry-Howard correspondence, but we ran out of time; at some point there will be another
