Translation of tensor in Spanish

I will built a function that will do all lowercase but meanwhile, I would be happy if it could be rewritten to lower case... Is it possible for you? They should all be lowercase, I did it inadvertently.
I have sent you my e-mail address. If you want to write me there, I could view the messages immediately. It would be easier than on the Vocabulix forum, as I'm not online often enough.
First, let me thank you for your answer. And how can I support you further? I'd be very happy about it if we could both help in each other in learning Spanish. 'Tandem' learning beats all other methods.
