Class HeckeAlgebraElt

Object
  HeckeAlgebraElt

public class HeckeAlgebraElt

extends Object

An element of a given HeckeAlgebra H_Z(G, H).

Author:

Mark McConnell

Constructor Summary

HeckeAlgebraElt(HeckeAlgebra alg)
Constructs the zero element in the algebra.

HeckeAlgebraElt(HeckeAlgebra alg, GroupElt g)
Constructs the element 1*(g) in the algebra.

Method Summary

HeckeAlgebraElt	add(HeckeAlgebraElt y) Returns a new HeckeAlgebraElt that's the sum of this and y.
boolean	equals(Object o) Returns true only when the underlying HeckeAlgebras are equal and the coefficients are termwise equal.
int	hashCode() Consistent with equals(java.lang.Object).
HeckeAlgebraElt	mult(HeckeAlgebraElt y) Returns a new HeckeAlgebraElt that's the product of this and y.
HeckeAlgebraElt	mult(long a) Returns a new HeckeAlgebraElt that's this times the scalar a.
void	setName(String x) Sets a name for toString() to return.
String	toString()

HeckeAlgebraElt

public HeckeAlgebraElt(HeckeAlgebra alg,
                       GroupElt g)

Constructs the element 1*(g) in the algebra.

Method Detail

equals

public boolean equals(Object o)

Returns true only when the underlying HeckeAlgebras are equal and the coefficients are termwise equal.

hashCode

public int hashCode()

Consistent with equals(java.lang.Object).

mult

public HeckeAlgebraElt mult(HeckeAlgebraElt y)

Returns a new HeckeAlgebraElt that's the product of this and y.

Throws:

IllegalArgumentException - If the underlying HeckeAlgebras aren't equal.

add

public HeckeAlgebraElt add(HeckeAlgebraElt y)

Returns a new HeckeAlgebraElt that's the sum of this and y.

Throws:

IllegalArgumentException - If the underlying HeckeAlgebras aren't equal.

mult

public HeckeAlgebraElt mult(long a)

Returns a new HeckeAlgebraElt that's this times the scalar a.

Throws:

IllegalArgumentException - If the underlying HeckeAlgebras aren't equal.

setName

public void setName(String x)

Sets a name for toString() to return. To remove the name, set it to null.

toString

public String toString()
