### 4 Ring Maps

#### 4.1 Ring Maps: Attributes

##### 4.1-1 KernelSubobject
 ‣ KernelSubobject( phi ) ( attribute )

Returns: a homalg submodule

The kernel ideal of the ring map phi.

##### 4.1-2 KernelEmb
 ‣ KernelEmb( phi ) ( attribute )

Returns: a homalg map

The embedding of the kernel ideal Kernel(phi) into the Source(phi), both viewed as modules over the ring R :=Source(phi) (cf. Kernel (4.2-1)).

#### 4.2 Ring Maps: Operations and Functions

##### 4.2-1 Kernel
 ‣ Kernel( phi ) ( method )

Returns: a homalg module
