{"id":"https://openalex.org/G8564692397","display_name":"Studies of fibred complex surfaces from diversified perspectives","description":"Smooth projective algebraic surfaces with a fibration over a smooth projective curve are studied through the local analytic or topological invariants such as Horikawa index and local signature. We gave an explicit formula for them for non-hyperelliptic genus 3 fibrations. Also we studied plane curve arrangements through multiple sections of relative Jacobian varieties (of small genus) and produced new examples of Zariski pairs.","funder_award_id":"24244002","funder":{"id":"https://openalex.org/F4320334764","display_name":"Japan Society for the Promotion of Science","doi":"10.13039/501100001691"},"funded_outputs":["https://openalex.org/W2019997741","https://openalex.org/W2022092506","https://openalex.org/W2056694330","https://openalex.org/W2057081423","https://openalex.org/W2086732364","https://openalex.org/W2142227090"],"funded_outputs_count":6,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":22360000.0,"currency":"JPY","amount_usd":283976.12,"amount_usd_basis":"daily_rate","recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"Grant-in-Aid for Scientific Research (A)","start_date":"2012-05-31","end_date":"2017-03-31","start_year":2012,"end_year":2017,"landing_page_url":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-24244002/","doi":null,"provenance":"kaken","lead_investigator":{"given_name":"Kazuhiro","family_name":"Konno","orcid":null,"role_start":null,"affiliation":{"name":"Osaka University","country":"Japan","ids":[{"id":"https://nrid.nii.ac.jp/nrid/1000010186869","type":"nrid","asserted_by":"kaken"}]}},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G8564692397","primary_topic":{"id":"https://openalex.org/T10061","display_name":"Algebraic Geometry and Number Theory","score":0.9525,"subfield":{"id":"https://openalex.org/subfields/2608","display_name":"Geometry and Topology"},"field":{"id":"https://openalex.org/fields/26","display_name":"Mathematics"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T10061","display_name":"Algebraic Geometry and Number Theory","score":0.9525,"subfield":{"id":"https://openalex.org/subfields/2608","display_name":"Geometry and Topology"},"field":{"id":"https://openalex.org/fields/26","display_name":"Mathematics"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"institution_awarded":[{"id":"https://openalex.org/I98285908","display_name":"The University of Osaka","ror":"https://ror.org/035t8zc32","country_code":"JP","type":"education","lineage":["https://openalex.org/I98285908"]}],"updated_date":"2026-10-16T03:01:01.000Z","created_date":"2026-07-13T04:17:19.000Z"}
