Solving the selfconsistent equation for renormalization factor λ which renormalizes the effect of the interaction in all orders of U, dependence of superconducting transition temperature on interaction in the strong coupling region is obtained. Resulting behavior of the transition temperature is consistent with physical intuition. T_e decreases in proportion to t^2 /  | U |  and T_e → 0 at | U | → ∞.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学理学部","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/14128"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0286-9640","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250774","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学理学部紀要","subitem_source_title_language":"ja"},{"subitem_source_title":"Bulletin of the College of Science.
