George Jerrard

George Birch Jerrard (* 1804 in Cornwell, Oxfordshire, England; † 23 November in Long Stratton, Norfolk, England, 1863 ) was a British mathematician.

He studied at Trinity College, Dublin from 1821 to 1827. Jerrard is known for his studies of equations of the fifth degree. For this, he found that she always carried a polynomial transformation to an equation of the form

Can be reduced, except this simplified equation, the so-called Bring- Jerrard normal form, only equations to be solved up to the fourth degree. Jerrards result quintic had previously been found by the mathematician Erland Bring in the case of the equation, however, Jerrard formulated his approach also for equations of higher degrees.
