New matrix formalism for heterotic string theory on a torus
Oleg V. Kechkin
A new Lagrange formalism based on the use of a single scalar (d+1)X(d+1+n) matrix potential is developed for the low-energy heterotic string theory with n U(1) gauge fields compact…

Hidden Symmerties in Dilaton--Axion Gravity
D. V. Gal'tsov, O. V. Kechkin
Four--dimensional Einstein--Maxwell--dilaton--axion system restricted to space--times with one non--null Killing symmetry is formulated as the three--dimensional gravity coupled si…
