Si studia, nell'ipotesi che sussista il principio di scambio delle stabilità, il problema agli autovalori che governa la stabilità lineare della quiete per un problema di Benard elettroanisotropo, in presenza di correnti di Hall e di ion-slip. Si risolvono due problemi agli autovalori dello stesso ordine derivanti dall'aver scomposto le perturbazioni nelle loro parti pari e dispari, espresse come somme di serie di Fourier di opportuni insiemi totali in spazi di Hilbert separabili. Si determinano le curve neutrali applicando il metodo di Budiansky-DiPrima Si prova l'effetto instabilizzante delle correnti elettroanisotrope.
