Format \u00een tradi\u021bia \u0219tiin\u021bific\u0103 a profesorului\u00a0Constantin Sibirschi<\/b>, fondator al teoriei invarian\u021bilor algebrici ai sistemelor diferen\u021biale \u0219i al acestei importante \u0219coli de cercetare din Republica Moldova, Valeriu Baltag a contribuit semnificativ la dezvoltarea \u0219i consolidarea direc\u021biei respective. \u00cen colaborare cu al\u021bi discipoli ai profesorului Sibirschi, el a participat la elaborarea unor polinoame invariante de mare utilitate \u00een teoria calitativ\u0103 a sistemelor diferen\u021biale polinomiale.<\/p>\n

Printre rezultatele sale remarcabile se num\u0103r\u0103 construirea unor polinoame invariante fa\u021b\u0103 de grupul transform\u0103rilor afine, care furnizeaz\u0103 condi\u021bii afin-invariante pentru determinarea multiplicit\u0103\u021bii totale a singularit\u0103\u021bilor finite ale sistemelor diferen\u021biale polinomiale generice. De asemenea,\u00a0Valeriu Baltag<\/b>\u00a0a realizat o clasificare a sistemelor diferen\u021biale cuadratice plane \u00een func\u021bie de num\u0103rul \u0219i multiplicit\u0103\u021bile punctelor singulare situate pe dreapta de la infinit. Aceste rezultate se \u00eentemeiaz\u0103 pe clasificarea familiilor de sisteme cuadratice dup\u0103 multiplicitatea total\u0103 a tuturor punctelor lor singulare finite.<\/p>\n

Prin activitatea sa \u0219tiin\u021bific\u0103, doctorul\u00a0Valeriu Baltag<\/b>\u00a0a contribuit la dezvoltarea matematicii moldovene\u0219ti \u0219i la afirmarea interna\u021bional\u0103 a rezultatelor ob\u021binute \u00een cadrul \u0218colii Sibirschi.
