Variational analysis of liquid crystals. (English) Zbl 07802844
Summary: This is an exposition of the role played by the calculus of variations in the field of liquid crystals, in particular the way it provides a sound foundation to the mathematical modelling and numerical study of their response to the confining material’s geometry and to external electromagnetic stimuli.
