X Y -pic User’s Guide Kristofer H. Rose h krisrose@ens-lyon.Fr i × Version 3.7, ±ebruary 16, 1999 Abstract X Y -pic is a package for typesetting graphs and diagrams using Knuth’s T E X typesetting system. X Y -pic works with most of the many formats available; e . g ., plain T E X, L A T E X, and A M S -T E X. Several styles of input for various diagram types are supported; they all share a mnemonic notation based on the logical composition of visual com- ponents . This guide concentrates on how to typeset “matrix-like” diagrams, such as commutative diagrams, in the following style: U y x % ( x,y ) # X × Z Y q p / X f ± Y g / Z was typeset by the X Y -pic input lines \xymatrix{ U \ar@/_/[ddr]_y \ar@/^/[drr]^x \ar@{.>}[dr]|-{(x,y)} \\ & X \times_Z Y \ar[d]^q \ar[r]_p & X \ar[d]_f \\ & Y \ar[r]^g & Z } Such diagrams have the following characteristics: Specified as a matrix of entries that are automati- cally aligned in rows and columns. Any entry may be connected to any other en- try using a variety of arrow styles all rotated and stretched as required. Arrows may be decorated with labels that are tied to a specified point along the arrow and extend in a particular direction; and arrows may be paired, cross, and visit/bend around other entries “on the way.” Several other styles of input are supported; a short survey of the possibilities is included last at the end along with information on how X Y -pic can be obtained.

Preface This guide explains some features of X Y -pic that are relevant to typesetting of “matrix-like diagrams” as used in, for example, category theory; please refer to the reference manual [8] for complete information on the described constructions. The guide assumes that you have some experience in using T E X for typeset- ting mathematics, e . g ., have studied [2, ch. 16–19], [3, sec. 3.3], or [9], and that X Y -pic is installed on your T E X system as described in the INSTALL file accom- panying the distribution.
