چکیده
In this paper, we prove two conjectures of Ulas ([21]) on two Diophantine equations of Ramanujan-Nagell type. In fact, we show that the following equations x + (2 + 1)2 = 2 + 2 + 2 + 2 + 1, x + 1 3 ( 2 − 1 ) 2 = 1 9 ( 49 · 4 − 11 · 4 + 1 ) have exactly four solutions.

Ternary Diophantine Equations via Galois Representations and Modular Forms
In this paper, we develop techniques for solving ternary Diophantine equations of the shape Axn + Byn = Cz2 , based upon the theory of Galois representations and modular forms. We subsequently utilize these methods to completely solve such equations for various choices of the parameters A, B and C . We conclude with an application of our results to certain classical polynomial-exponential equat...

A well-known result of Beukers [3] on the generalized Ramanujan-Nagell equation has, at its heart, a lower bound on the quantity |x2 − 2n|. In this paper, we derive an inequality of the shape |x3 − 2n| ≥ x4/3, valid provided x3 6= 2n and (x, n) 6= (5, 7), and then discuss its implications for a variety of Diophantine problems.
متن کاملA generalized Ramanujan-Nagell equation related to certain strongly regular graphs
A quadratic-exponential Diophantine equation in 4 variables, describing certain strongly regular graphs, is completely solved. Along the way we encounter different types of generalized Ramanujan-Nagell equations whose complete solution can be found in the literature, and we come across a problem on the order of the prime ideal above 2 in the class group of an imaginary quadratic number field, w...
