No Derivation in the Frame: The Complete Einstein–Cartan Search for the Vacuum Conversion and Its Terminal Position

open access: yes
The vacuum catastrophe, in the form this program has carried it, is a conversion problem. A budget of vacuum degrees of freedom must be converted into the observed vacuum energy density, and the conversion fails at exactly one step: physics must supply an entropy per unit horizon area, s/a_cell = 1/(4l_P^2), from inside the Einstein–Cartan (EC) /

Ομάδες Coxeter μέσω πινάκων Cartan

open access: yes
Στόχος αυτ΄ής τη διπλωματικής είναι η μελέτη των πεπερασμένων ομάδων Coxeter, καθώς και η ταξινόμησή τους. Αυτό θα το επιτύχουμε μελετώντας και ορίζοντας τους πίνακες Cartan, όπως και την αντίστοιχη δράση τους.This thesis is about finite Coxeter groups ...
