about

The notion of singular quadratic form appears in mathematical physics as a tool for the investigation of formal expressions corresponding to perturbations devoid of operator sense. Numerous physical models are based on the use of Hamiltonians containing perturba­ tion terms with singular properties. Typical examples of such expressions are Schrodin­ ger operators with O-potentials (-<_20_2b_20_ad29_20_and20_hamiltonians20_in20_quantum20_field20_theory20_with20_perturbations20_given20_in20_terms20_of20_operators20_of20_creation20_and20_annihilation20_28_p28_ _2b_="" _ad29_="" and="" hamiltonians="" in="" quantum="" field="" theory="" with="" perturbations="" given="" terms="" of="" operators="" creation="" annihilation="">
