Is the use of mathematical axioms good or bad in mathematics? Is it difficult to prove axioms?

Some people consider mathematical axioms as points of strength of mathematics, other say that axioms are points of weakness. My question is why?! Is it so difficult to prove mathematical axioms?

Ette Etuk

Google "M.Sc. topics in Queueing Models" and topics currently considered in some universities will be seen.

Radi Petrov Romansky

sample suggestions for theses topics 9if this is the qoal of the question):

1. Probability research (by Markov chain) and study of processes in business information systems with cloud services.

2. Analytical Modeling (with Markov Chain) of Enterprise Information Systems Access Control Environment.

3. Model study of the access to resources in an e-learning environment using the Markov chains' apparatus

Mohamed I. Riffi

Dear Ette Etuk,

Thanks for your answer.

Mohamed

Dear Radi Petrov Romansky,

Thanks so much for your very good ideas and suggestions.

these are real topics that my graduates have done in recent years
