As a byproduct, we obtain a natural generalization of the parallel sum and parallel difference, as well as the Lebesgue-type decomposition. To demonstrate how this operator approach works in application, we derive the corresponding results for operators acting on rigged Hilbert spaces, and for representable functionals of ⁎-algebras.}, year = {2021}, eissn = {1873-1856}, pages = {125-143}, orcid-numbers = {Tarcsay, Zsigmond/0000-0001-8102-5055; Titkos, Tamás/0000-0002-3891-7020} } @article{MTMT:31033608, title = {Maps preserving absolute continuity and singularity of positive operators}, url = {https://m2.mtmt.hu/api/publication/31033608}, author = {Gehér, György and Tarcsay, Zsigmond and Titkos, Tamás}, journal-iso = {NEW YORK J MATH}, journal = {NEW YORK JOURNAL OF MATHEMATICS}, volume = {26}, unique-id = {31033608}, issn = {1076-9803}, year = {2020}, pages = {129-137}, orcid-numbers = {Gehér, György/0000-0003-1499-3229; Tarcsay, Zsigmond/0000-0001-8102-5055} } @article{MTMT:31038500, title = {Operators on anti-dual pairs: Lebesgue decomposition of positive operators}, url = {https://m2.mtmt.hu/api/publication/31038500}, author = {Tarcsay, Zsigmond}, doi = {10.1016/j.jmaa.2019.123753}, journal-iso = {J MATH ANAL APPL}, journal = {JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS}, volume = {484}, unique-id = {31038500}, issn = {0022-247X}, year = {2020}, eissn = {1096-0813}, orcid-numbers = {Tarcsay, Zsigmond/0000-0001-8102-5055} } @article{MTMT:30349889, title = {Lebesgue type decompositions for linear relations and Ando's uniqueness criterion}, url = {https://m2.mtmt.hu/api/publication/30349889}, author = {Hassi, S. and Sebestyén, Zoltán and De, Snoo H.}, doi = {10.14232/actasm-018-757-0}, journal-iso = {ACTA SCI MATH (SZEGED)}, journal = {ACTA SCIENTIARUM MATHEMATICARUM (SZEGED)}, volume = {84}, unique-id = {30349889}, issn = {0001-6969}, year = {2018}, pages = {465-507} }
