Piergiorgio Odifreddi (born 13 July 1950, in Cuneo) is an Italian mathematician, logician, scholar of the history of science, and popular science writer and essayist, especially on philosophical atheism as a member of the Italian Union of Rationalist Atheists and Agnostics. He is philosophically and politically near to Bertrand Russell and Noam ...
t. e. Mathematical logic is the study of formal logic within mathematics. Major subareas include model theory, proof theory, set theory, and recursion theory (also known as computability theory). Research in mathematical logic commonly addresses the mathematical properties of formal systems of logic such as their expressive or deductive power.
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. Second, Boolean algebra uses logical operators such ...
Giuseppe Peano ( / piˈɑːnoʊ /; [1] Italian: [dʒuˈzɛppe peˈaːno]; 27 August 1858 – 20 April 1932) was an Italian mathematician and glottologist. The author of over 200 books and papers, he was a founder of mathematical logic and set theory, to which he contributed much notation. The standard axiomatization of the natural numbers is ...
Christine Ladd, sometimes known by the nickname "Kitty", [1] was born on December 1, 1847, in Windsor, Connecticut, to Eliphalet, a merchant, and Augusta ( née Niles) Ladd. During her early childhood, she lived with her parents and younger brother Henry (born 1850) in New York City. [2] In 1853 the family moved back to Windsor, Connecticut ...
Structure (mathematical logic) In universal algebra and in model theory, a structure consists of a set along with a collection of finitary operations and relations that are defined on it. Universal algebra studies structures that generalize the algebraic structures such as groups, rings, fields and vector spaces.
Laura Toti Rigatelli (1941-2023) was an Italian historian of mathematics, founder of the Center for Medieval Mathematics at the University of Siena, [1] biographer of Évariste Galois, [2] and author of many books on the history of mathematics. [3] Toti Rigatelli is originally from Florence. [1]
Algebraic logic. In mathematical logic, algebraic logic is the reasoning obtained by manipulating equations with free variables . What is now usually called classical algebraic logic focuses on the identification and algebraic description of models appropriate for the study of various logics (in the form of classes of algebras that constitute ...
