Period-doubling critical behavior

B - Bicritical alphabet
Description Two period-doubling subsystems with unidirectional coupling of fixed magnitude, both brought at the chaos threshold by tuning of their control parameters. RG equation The fixed point The orbital scaling factors Critical multipliers Relevant eigenvalues Codimension CoDim=7 (restr. 2)	Basic model at B=0.375:   Scaling of the parameter plane with factors show enlarged figure   Scaling of the bicritical attractor with factors show enlarged figure
