It presents a detailed exposition of the methods of regularized solution of inverse problems based on the ideas of Tikhonov regularization, and shows the different forms of their applications in both linear and nonlinear methods of geophysical inversion. It's the first book of its kind to treat many kinds of inversion and imaging techni 410 0$aMethods in Geochemistry and Geophysics 606 $aInversion (Geophysics) 606 $aGeophysics$xMeasurement 606 $aFunctional analysis 615 0$aInversion (Geophysics) 615 0$aGeophysics$xMeasurement. 615 0$aFunctional analysis. 676 $a550.1515 700 $aZhdanov$b Mikhail Semenovich$0771808 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910797356103321 996 $aInverse theory and applications in geophysics$93814464 997 $aUNINA LEADER 01899nam2 2200421 i 450 001 MIL0157994 005 20251003044226.0 010 $a8878120227 020 $aIT$b94-540 035 $a(OCoLC)885614431 100 $a20181018d1993 ||||0itac50 ba 101 | $aita 102 $ait 181 1$6z01$ai $bxxxe 182 1$6z01$an 183 1$6z01$anc$2RDAcarrier 200 1 $aˆ4: ‰Indice relativo e manuale 210 $aRoma$cAssociazione italiana biblioteche$d1993 215 $aVII, 979 p.$d25 cm. 461 1$1001LO10306492$12001 $aClassificazione decimale Dewey$fideata da Melvil Dewey$v4 606 $aClassificazione decimale Dewey$2FIR$3CFIC018997$9E 676 $a025.4$9ATTIVITA DELLE BIBLIOTECHE, DEGLI ARCHIVI, DEI CENTRI D'INFORMAZIONE.
