Abstract:
This paper presents an algorithm for proving plane geometry theorems stated by text and diagram in a complementary way. The problem of proving plane geometry theorems involves two challenging subtasks, being theorem understanding and theorem proving. This paper proposes to consider theorem understanding as a problem of extracting relations from text and diagram. A syntax–semantics (S2) model method is proposed to extract the geometric relations from theorem text, and a diagram mining method is proposed to extract geometry relations from diagram. Then, a procedure is developed to obtain a set o

Abstract:
Understanding and constructing proofs of mathematical theorems is a fundamental component of mastering mathematics and developing the logical apparatus. In addition, the theorems in mathematical textbooks are often only understandable through their proofs. However, students sometimes lack the precision needed to write detailed proofs and the understanding of basic proving concepts. In this paper, we propose the use of interactive theorem provers by math teachers with the goal of improving students' mathematical proving skills and understanding of logical rules.

Automated theorem provers have traditionally relied on manually tuned heuristics to guide how they perform proof search. Deep reinforcement learning has been proposed as a way to obviate the need for such heuristics, however, its deployment in automated theorem proving remains a challenge. In this paper we introduce TRAIL, a system that applies deep reinforcement learning to saturation-based theorem proving. TRAIL leverages (a) a novel neural representation of the state of a theorem prover and (b) a novel characterization of the inference selection process in terms of an attention-based action

The Cauchy Group Theorem is proved by proving the existence of an order element in a finite group , here is a prime divisor of , and is the order of group .

Abstract:
AbstractWe generalize Löwner's method for proving that matrix monotone functions are operator monotone. The relation x ≤ y on bounded operators is our model for a definition of C*-relations being residually finite dimensional.Our main result is a meta-theorem about theorems involving relations on bounded operators. If we can show there are residually finite dimensional relations involved and verify a technical condition, then such a theorem will follow from its restriction to matrices.Applications are shown regarding norms of exponentials, the norms of commutators, and “positive” noncommutativ
