The same kind of result would be easier to prove in 3d: This is all pretty fascinating to me.

There is certain diverse class of diagram that is found in a variety of branches of mathematics and which all share this property: But, several interesting and useful libraries are fundamentally incompatible with the monadic interface.

Said homework then has to be marked. We argue that symmetric semi monoidal comonads provide a means to structure context-dependent notions of computation such as notions of dataflow computation computation on streams and of tree relabelling as in attribute evaluation. Abstract In this tutorial, we describe how to use monad transformers in order to incrementally add functionality to Haskell programs. It would be commutatiev nice if I could actually create these as 3-d objects and then just export some projection of them, possibly suitably ray traced.

Would the parties involved object to the paper being scanned and put on the nLab?

The second is the so-called swallowtail relation see Figure 25 on page 40 of HDA4. I know zero about what such scripting is capable of. December by Graham HuttonErik Meijer posted to combinators monads parsing by andrewbutterfield on I like the touchpoint so much better for everything, including blender.


Commutative monads, diagrams and knots

I think this is the nicest version of this diagram. The braiding does not play any role in this game!

Unfortunately, they will probably look horrible in older browsers, like Netscape 4. Based on Actor-Network Theory and Bruno Abstract This is a tutorial for mathematically inclined functional programmers, based on previously published, peered reviewed theoretical work.

I am reediting the text of the Monacs and getting it ready for a publisher. This paper shows how list comprehensions may be generalised to an arbitrary monad, and commutatve the resulting programming feature can concisely express in a pure functional language some programs that manipulate state, handle exceptions, parse text, or invoke continuations.

VDM descriptions of programming languages differ from the original Scott—Strachey style by making extensive use of combinators which have a fixed operational interpretation.

I had an attempt at creating some categorical surfaces using blenderwhich is a splendid piece of open source software which you can use to make movies knote Shrek or Monsters Inc.

Diagrans first represents the associator natural transformation in a monoidal category see the Hopf monads paper linked above for the details. In particular I thought I would make use of our hopefully brief sojourn at WordPress and take the opportunity to embed some videos but then I was told how I could do commutagive at our usual place.

I find the area your question covers very interesting and am looking forward to seeing what answers people come up with. Modeling Surface Diagrams I put them on a teeny-tiny flash drive this morning which I forgot to put into my pocket. We discuss the implementation, and use some examples to illustrate the usefulness of this construction.


Thanks for the suggestion. I suspected that these diagrams might also be lurking in Bayesian networks and other kinds of graphical models used in machine diqgrams.

Abstract We argue that symmetric semi monoidal comonads provide a means to structure context-dependent notions of computation such as notions of dataflow computation computation on streams and of tree relabelling as in attribute evaluation. Mike Shulman on March 26, For instance, when we draw pasting diagrams in a bicategory, there is a theorem we are implicitly invoking saying that the result of the pasting is uniquely determined once we choose a bracketing of the source and target.

Thus, in the presence of two John Baez on March 29, 7: This paper describes the history of Haskell, including its genesis and principles, technical contributions, implementations and tools, and applications and impact. Junepp. It’s especially geared at applications to quantum mechanics, namely “dot”-style diagrams of Frobenius algebras for complementary observables Coecke, Duncan, arXiv: Modeling Surface Diagrams Not quite sure why but I found the static associator surface in the paper easier to comprehend than the video although I had to intuit the hidden surface in the static image.

Peter Freyd and David Yetter I’m not sure whether this write-up adds anything on top of the existing resources, but Jim Blinn, a graphics researcher at Microsoft Research has written up some course notes on tensor diagrams:
