What are the ∀ Σ b 1 - consequences of T 12 and T 22 ?

چکیده
We formulate schemes (M1) and (M2) of the “typical” ∀Σ1-sentences that are provable in T 1 2 , respectively T 2 2 . As an application, we reprove a recente result of Buss and Kraj́iček which describes witnesses for the ∀Σ1-sentences provable in T 1 1 in terms of solutions to PLS-problems.

*-σ-biderivations on *-rings
Bresar in 1993 proved that each biderivation on a noncommutative prime ring is a multiple of a commutatot. A result of it is a characterization of commuting additive mappings, because each commuting additive map give rise to a biderivation. Then in 1995, he investigated biderivations, generalized biderivations and sigma-biderivations on a prime ring and generalized the results of derivations fo...

Brucellosis, produced by Brucella species, is a disease that causes severe economic losses for livestock farms worldwide Due to serious economic and medical consequences of this disease, many efforts have been made to prevent the infection through the use of recombinant vaccines based on Brucella outer membrane protein (OMP) antigens. In the present study, a wide range of on-line prediction sof...
متن کاملAxiomatizations and Conservation Results for Fragments of Bounded Arithmetic
This paper presents new results on axiomatizations for fragments of Bounded Arithmetic which improve upon the author’s dissertation. It is shown that (Σi+1 ∩Π b i+1)-PIND and strong Σ b i -replacement are consequences of S 2 . Also ∆ b i+1 -IND is a consequence of T i 2 . The latter result is proved by showing that S 2 is ∀∃Σ b i+1 -conservative over T i 2 . Furthermore, S i+1 2 is conservative...
متن کاملConservative fragments of S12 and R12
Conservative subtheories of R 2 and S 1 2 are presented. For S 1 2 , a slight tightening of Jeřábek’s result [18] that T 0 2 ∀Σ1 S 1 2 is presented: It is shown that T 0 2 can be axiomatised as BASIC together with induction on sharply bounded formulas of one alternation. Within this ∀Σ1-theory, we define a ∀Σ0-theory, T−1 2 , for the ∀Σ0-consequences of S 1 2 . We show T −1 2 is weak by showing...
