Biography

Il-Young Son received the B.Sc, M.Sc, and Ph.D. degrees in electrical engineering from Rensselaer Polytechnic Institute (RPI), Troy, NY, USA, in 2001, 2006, and 2018, respectively. His M.Sc. thesis was on Diffuse Optical Tomography and Functional NIR imaging while the topic of the Ph.D. thesis was on the application of polarimetry in passive radar imaging. After receiving his doctorate, he was a Postdoctoral Researcher with RPI in 2019, where he conducted research on autofocus techniques for SAR imaging and interferometric multistatic passive radar, incorporating real data processing to both areas. His research interests include passive radar imaging, radar polarimetry, and application of optimization techniques to radar data processing.(Based on document published on 16 January 2020).

Working jointly in the equivalent categories of MV-algebras and lattice-ordered abelian groups with strong order unit (for short, unital ℓ-groups), we prove that isomorphism is a sufficient condition for a separating subalgebra A of a finitely presented algebra F to coincide with F. The separation and isomorphism conditions do not individually imply A = F. Various related problems, like the separa...Show More
