I have a custom content type with a field (id is field_link_to_persona) that is multi-valued text. In my UI I have checkboxes that correspond to values in that field and if I uncheck the box and save I want to remove the value from the field. I load the node like this: $ nodes =Read more

Is there a multi-valued fixed point theorem for complex projective Hilbert spaces, or equivalently, Kahler manifolds with positive curvature? In other words, an analogue of Kakutani’s theorem for complex projective Hilbert spaces. I am aware of Frankel’s theorem (https://msp.org/pjm/1961/11-1/pjm-v11-n1-p12-p.pdf) (theorem 4) which assures a fixed point for holomorphic functions from such a space to itself.Read more
