# direct product

## A construction of direct product in the category of continuous maps between endo-funcoids โ โ โ

Author(s): Porton

Consider the category of (proximally) continuous maps (entirely defined monovalued functions) between endo-funcoids.

Remind from my book that morphisms of this category are defined by the formula (here and below by abuse of notation I equate functions with corresponding principal funcoids).

Let are endofuncoids,

We define

(here and are cartesian projections).

**Conjecture**The above defines categorical direct product (in the above mentioned category, with products of morphisms the same as in

**Set**).

Keywords: categorical product; direct product
